tubbedbaggedstockfloored65 · November 21, 2013

hey fellow ratsuners hows it going. im sort of new to this web site but i give props to everyone on here and all the knowledge you guys have provided me and ive learned so much thru this website/ community, my first datsun was a lowered 76 datsun 620 with rust and holes to match and i still have it and love it to death...but recently picked up a 75 datsun 620 4x4 and dont know entirely to much about it

i have swapped out water pumps since old one stuck out past alternator and crank pulley about quarter of an inch , flushed radiator and a few other dinky things and still neeed to purchase a windshield for front and rubber seal...does anyone know where i can get the rubber trip for front window ? or will a company installing my new window provide that?

anyway please guys post your 4x4s and tips and what not to help me out i am gunna post pics as soon as i take some after work tomorrow , REALLY stoked about this truck got some new tires and tread for it not much but 31s will do for now

does any of you smart ratsun people know how to get a lift kit or raise it up even more so i can put biggger meatier tires on it? im pretty young and new to the 4x4 world and not sure exactly what kind of frame or axles or running gear its on so anything you guys can tell me would be appreciated and much obliged. posting pics tomorrow!

lets all post your 4x4 620s! :)

Nice 620. I love the 4x4's. The windshield installer can provide the rubber, or you can buy one online by itself or in a bundle with other gaskets. If it is the only weatherstrip you need, I would let the glass guy get it.

There are several good 620 4x4 threads in progress here. You can try the search bar, but you may have better luck Googling something like "620 4x4 ratsun". Members Boxcar and J2edeye know everything they is to know about the 4x4 620 drivetrain business. :)

The water pump may have been from a Z car.

jastrunk97 · November 21, 2013

Darn..Been eyeing that thing for awhile now on CL....:/ Glad you got a good home though! :) Best of luck with it! P.S I got a windshield gasket from Ebay, it looks great and is real nice, I havnt installed it yet but am looking forward to it.

OneFreakyMF · November 21, 2013

I'd seen that one on CL as well. Looked like a good project. Lifting it might be an adventure. As far as I know, the 620's never came from the factory with 4wd. It was a dealer/aftermarket option. I've heard of several different axle and spring configurations. Mine had Jeep CJ front springs, stock rear springs, and Dana 44 axles. The rear axle had spring perches that were six inches tall! Very goofy looking!

What are your long term plans for this lil rig??

tubbedbaggedstockfloored65 · November 22, 2013

well thanks sandy mush and yea its been on there for a while so i decided to pick it up since i was fairly close and love datsuns and always wanted a 4x4 and i have a few long term plans but since i lost my job and tryin to put myself thru school im in a low budget project but i definaanly would like to get some 35s or bigger for it but not sure if it will take it it would rub and interfere so thats why i would like to raise it somewhow whether i can raise the body or the running gear.. if any of you reading this have a clue where or how to get something available to raise it up and i have seen any 4x4 posts ill keep looking and i would also need to weld in new drivers floor board and all 4 floor mounts in the truck are shot and rusted thru the whole cab shakes and rattles haha good times :) and dash is creacked in a bajillion places and ugly does anyone know where or if they make a carpet pad to cover the dash or should i get like a datsun cloth or american flag and use tacks to pin it to the dash just to cover it and i also need ti pick up a few things like the drivers side door panel cover it does not have one and i also need to get a heater box cover its cracked and has ducktape all over it so it wouldnt work worth a darn..and thanks i will take your advice and have the window guys provide the rubber

i have yet to start it i changed the water pump pulley but i need to wire in a fan in front of the radiator because there is not enoughr ooom in betweeen the water pump pulley and the radiator

oh and i dontt have any reverse lightsi replaced all the fuses and bulbs but still no reverse lights maybe where it goes into tranny?

ill have to crawl under neath and cher her out..its definanlty ewasier to get under this one than my other one thats lowered and sittin on bump stops haha :p ill post more pictures tryin to upload now!

tubbedbaggedstockfloored65 · November 22, 2013

stupid mice who got into some trash and tore up seat and just about everything else , little bastards there probably the culprets to the reason why i have no reverse lights

tubbedbaggedstockfloored65 · November 22, 2013

i added an extra grill emblem that i had laying around and straightened out the little front apron that was bent from PO and picked up some cheap wheels that would fit over my hubs :) as you can see the seat and iinside has seeen way better days haha :p owell

tubbedbaggedstockfloored65 · November 24, 2013

A body lift is the budget way to get some lift. I wouldn't recommend that with rusted out body mounts though... Re-arched springs will give some lift too, but you'll most likely need longer drive lines and double cardan joints if the u joint angles to to be too much...

JC Whitney has dash caps and carpet kits. Neither are of very good quality.

The steering box was my first mod to the 78 620 4X4 I bought last year. The stock one is to small for any decent sized tires and the ratio and 6 turns lock to lock sucks. Have a 07 jeep grand Cherokee box in mine now. Next suspension mods will be coil overs and 4 links front and rear.

This might help ya.

The lift question is best handled with custom springs and mounts.

And tire size : I never exceed 35" on a rat conversion . But that's just me.

I will fallow you're build. Nice rig congrats........

Boxcar · November 24, 2013

I used 3"x2" x . 250 rec tube to double the rear frame / stock 720 rear main spring with Toyota liefs added to get the desired ride hight and 3" over cross blocked shackles. This will net you about 7" over where you are now.

Up front I run Toyota 1st gen. 2" lift rears / a shackle reverce system and 2" over cross blocked shackles.

You are gonna need a tall jack as this system has a bunch of droop.

Will now clear 33's with out body mods. 35's will require trimming.

Hope this helps.

tubbedbaggedstockfloored65 · November 24, 2013

box car and turbo620 both of you have bad to the bone rigs, i feel like a big retard tho im pretty young and inexperienced and never done anything with 4x4 so box car all the stuff and info you sent me i dont really understand some of it yes but most of it i couldnt do myself and wouldnt no where to start :( i had to sell my welder and get rid of my compressor and cutter and waht not so i dont know what to do i need to have someone help me if i made it worth there while big time, just dont know who can help or if anyone would help

OneFreakyMF · November 24, 2013

so your not sure if i can get a lift kit or something to lifet this? am i pretty much stuck at this heighth?

I don't think you'll find a lift kit for a 620 anywhere but you are by no means stuck with where you are. In my mind, anything is possible. Hell, my 620 build involves a 4.3L, couple of transfer cases, hydraulic steering, ARBs, & 36" iroks! It just takes time, MONEY, ability to do the fab work, and the drive to see it through to the finish! That is the most important, FINISH! Far too often projects are started and never completed. That's how I picked up my 620.

Take your time and research everything. Yes, you want it taller but bigger is not always better. Are you wanting to wheel this rig or turn it into a pavement princess? Lil of both? That's what I mean by long term goals.

My opinion, if ya want to street drive it with a lil trail use then keep it where it is, take care of all the maintenance issues, and drive it! A princess... Then a full blown restore would be in order. A wheeler... Options are almost endless but most likely will not be streetable.

tubbedbaggedstockfloored65 · November 24, 2013

i have the drive and am not gunna give up on this and if i can ill keep it til im 70 years old and wearing diapers

i have 31s on it but would at least like 36s on it that would be cool, and yea i dont have to ways to fab it anymore ince i got rid of all my stuff and dont know anyone in the area that would help me,, i would like to take the old lady out and sling some mud and not worry about gettin stuck or rubbin tires on fenders and bigger wider tires are just cooler lookin for a 4x4 stance, but since ive got the stock l20 i dot really have much hoorses under hoood to get me out of a few mud holes so i think wheelin is out of the question, ill probably drive it on street mostly but i do have a mile long muddy drive way and weather is shitty here and would like to have better traction gettin around ewspecially if it snows

id like to make it the best wheeler i could but keep it street worthy!

and your a lot smarterr than i am iim not new to cars and motors and waht not but datsuns and especiaally 4x4s yess im a biig noob and rookie,

but i defiannlty would be driving this on the street more than i would be hittin mud but i definanly like the mud covered truck look

tubbedbaggedstockfloored65 · November 25, 2013

what size tire are you guys runnin? you said you never have over 35s? well what size tire are you runnin? and what are 3 of the cheapest performance or beef up mods that i can do ?

Boxcar · November 25, 2013

#1 clean up you're ignition, exhaust and carb. Get them working perfectly.

#2 Dial in the suspension that you already have.

#3 fix all of the issues that you have now with the truck.

These are the least expensive things that will make a HUGE difference right now.

Then Later, when you have the means to alter or upgrade the truck tackle the full on build.

You're truck is already very cool. Very rare , and something to be proud of right now.

Take you're time , do it right. It'll be worth the effort.

And don't cut it unless you have to..

In order to run 36" tires on a dealer prep Datsun 4x4 you will need to do MAJOR alterations.

The rig pictured in my build is not a dealer prep rig .

I started the build with a NW ATV 521 Donner, but ended up using almost none of it. To far gone.

So the build went the direction that you se.

60" 44's front and back with chrome molly shafts , lockers , long travel shocks ETC. ETC. ETC.

All of this was done just to clear 33's with an un cut body.

With long bump stops I could run 35's but that would require deeper gearing than I want to run.

Tire greed is a common ailment. And , cool looking aint worth shit in the woods.

Unless you are planning a rock crawler 35's are all you will ever need.

Are you're cab mounts gone or you're bed mounts?

If it's the bed mounts, I have a bunch of pre cut hat bars left over from a build that you may have . Just come and get them. Astoria isn't far from you , and a day in my shop will answer a years worth of questions..... PM me for my #

tubbedbaggedstockfloored65 · November 25, 2013

well i am not entirely to sure if its dealer or thrown togther by someone i am not entirely sure how to tell without taking anything apart? how can i tell what front and rear axle it is? its not that good of a job of the floor shifter all to the right so it leads me to beleive it was some one who owned it

yea i just want dont wanna get stuck, i no its not about what your driving, its how you drive it i just still want to get the biggest tires i can, which im not sure i can put on there without effexting anything

and not the ones in the bed and not the two up front but the 4 inside 2 on eaach side as you open door on floor

tubbedbaggedstockfloored65 · November 25, 2013

i have nothing to make it to astoria oregon otherwise i would, my truck i just dont trust it

tubbedbaggedstockfloored65 · November 25, 2013

now what about motor mods? is there anything i can do with it all i need to do is replace fuel filters plugs and oil change and what not but what can i do to give me more oomf! , maybe pair of headers or diff intake and carb, or is that just gunna dscrease life of motor

1975 4X4? second datsun first 4x4 datsuns shall rise!
