620 any thoughts?

What exactly was done to this truck? I love it this is what Im shooting for on my 620 I have a 720 thinking about changing the axls and everything to make it 4x4 since the 620 is 2wd. any thoughts? should i just put blocks to lift the truck?

[Cuts metal like mad]

720 4wd is IFS which would require welding in the entire front frame section to do properly and thats the easy way...

hmm well maybe i wont do a 4wd swap seems like it would be a lot of work...any thoughts on the lift because that pic. looks sweeeeeeettttt

That's not IFS. I can see the spring perches. It's either Jeep or Toyota parts.

 

The EASY way to convert a 2WD 720 to 4WD start with a 4WD truck. It is far eaisier to swap the body than to try to adapt the frame. Unless you want to go with the Solid axle front end, in which it doesn't matter what you start with as the whole front suspension is removed anyway.

a solid axle swap would be way easier... but any 4wd swap is gonna require welding.

 

if your truck is a 78-79, you can use d21 2wd lift spindles, but they require the use of the d21 brakes as well.

Hes wants to use a 720 4x4 to make his 620 4wd...

[ronnie93212]

its a 78 620 2wd datsun and a 80 720 4x4 im wanting to make the 620 a 4x4

Dude building a 4x4 is a bitch! Trust me! The hard part is swapping the cab and bed.

[Cuts metal like mad]

if you combine 2wd lift arms, and 2wd lift spindles you can get like 4-5" suspension lift, throw in a 1-2" body lift and we're talkin 5-7" of total lift in the front...

 

if your only after a lift and don't plan on doing any serious offroading... I mean do the above along with a pathfinder se v6 rear axle (factory lsd) and you can still go places that will probably scare you (if you haven't done much offroading)

Not if you have a forklift and a Donor Truck;)

 

The truck in the pic is the one in a museum, built by spencer Low's company that did conversions. Most were done with a Jeep D20 transfer case and D30 front axle.

 

I was lucky, I picked up a longbed 4x datsun and put it on the forklift, cut all the drivetrain out and welded it in my shortbed.

 

Voila! weekend 4x conversion. YMMV.

a friend and I are about to do a 78 620 kc 2 wd swap to a 80 720 kc 4x4.

my question ice =

what is going to be " the hard part of the swap" I just want to make sure we get all our ducks in a roll before we get it started..

[Madness]

it's "ducks in a row" sorry that stuff drives me nuts.

No, you don't know what Icehouse had. He did have a donor truck. Two 620s so the cab and bed mounts matched. He also used a crane, much bigger than your forklift. He said that was hard and he had the easy job.

 

Your 720 frame and body don't even line up with the 620 so you'll be modifying or rebuilding body mounts. Welding still required if you try to put a 620 cab and body onto a 720 frame.

 

Icehouse has a thread on his 4x4 conversion with pics. Look it up. His was 620 kingcab 2wd to 620 kingcab 4x4

[420n620]

madness, your right, when I see misspelling it drives me nuts also, my bad

 

 

Bleach, I read ices swap aready, 620 looks nice,

I thought there was something like the steering coulmn, gas tank, or what ever might occur while removing the cab and bed because he said it was a bitch to swap.

 

about the 78 620 KC 2wd body swapped to the 80 720 KC 4x4, this is what I've been told..

 

If both trucks are King Cab, there should be no problems. If you have an '80 720 everything should fit because that year only also used the L series motor. I have had an '80 4X4 apart and the tranny was the same length as the 620 but measure them both for length. As long as they are the same length it will fit. (the 620 will be 31.5" and the 720 should be the same) The tranny mount should be the same but if not use the 620 auto one.

 

IF the 720 is a long bed, the KC cab will fit but the front two box mounts won't fit to the box. This is the frame I used. I cut the two mounts off and welded on about 10" back so they would bolt to the shorter KC bed. You could maybe just leave them, I don't think they are in the way, or maybe just cut them off?

The KC and the long bed truck frames are basically identical except for these two bed mounts.

****** ****** ******** ******* ********

 

When I get over to my friends house tomorrow, I'll measure the body mounts and transmission, I don't want a bunch of hidden surprises...
