New to me 620

Recommended Posts

My 79 620 door VIN plate doesn't look anything like that one.

 

The "incomplete vehicle" reference probably means it was originally sold to a US company or an individual as a running cab and chassis only without a bed. US companies would special order trucks this way, then mount a flat bed, tool service bed,  chassis mounted camper, or something other than a regular bed. 

 

Since the tag says the truck was mfg in 2/79 I would guess that is the year the cab and chassis vehicle first sold to a US company or even a customer, probably special ordered. 

I doubt the vehicle  came with an alternate  from Japan with an alternate bed, but suppose it is possible.  

 

But,  all the supporting owner's manual and supporting paper work says 1978. I speculate it was actually manufactured in 1978 and could have been sitting in Japan for that long, or at a US distribution facility, or even at a dealer. Then, the company who manufactured the service bed or camper then generated the new 1979 VIN sticker when they finalized their modifications and when it sold to a customer.  The original antenna holes on the passenger side cab leg support it being a 1978 truck (or earlier, but I doubt it.)

 

Also the dash does not have center vents for the AC original, nor does the center console have the control switch where the upper delete plate is. This vehicle more than likely never had original or aftermarket AC.    

 

Hope this helps!

P.S. It also doesn't have a condenser in front of the radiator, another supporting fact it didn't have AC.

 

And DatzenMike's observation about the fender badges not having the 1979 Datsun "by Nissan" fencer badges also supports it is a 1978 620.

That chrome bumper isn't. The tail pipe is normally a little closer to the left rear tail light.

 

Have never ever seen that style build tag on the door jam. You can see the holes for the screws. Looks somewhat official. I think the Cab/Chassis was '78-'79, although there were Camper models before this.

Ok. And that isn't the tail pipe. It looks like a camper tie down point or something.  The exhaust stops at the muffler under the bed for some reason.  So it's a 78? Just sold in 79 then?

I would say a '78 cab on a '79 frame. Since the bodies are (virtually) the same, there is no real fraud here.

 

All Cab/Chassis car numbers start ELH 620 ?????? as this one does... ELH 620 360,432

 

Car numbers are 310,001 - 375,000 for '78 It would seem this is a '78 year number...

Car numbers are 357001-?????? for '79

 

 

The top of the frame just forward of the right side engine mount and behind the alternator also has the car number stamped into the steel. Wire brush or sand paper will bring it up.

 

The Vehicle Emission Control Information is '78. They are very strict about the emission sticker. It must apply to the year stated.

The glove box manual is '78

Does say incomplete vehicle at bottom.

 

What are the numbers at the very bottom????

Ok as long as I dont run into issues with parts and title stuff it being possible different year cab and chassis I'm not worried about it. It is interesting how they did things back then. I'm unsure of the numbers down there. They dont look much cleaner in person.  Anyways I put new spark plugs, cap,and rotor on it yesterday. Seems to have helped the dieseling a lot. I'm happy with it now. I have a slight valve cover gasket leak which doesn't surprise me.  What brand do you guys recommend? Btw thanks for all the info on this old girl.

Mike knows much more about these than I do, he’s prob right about the year. 

 

The good  news is, most of  the operating parts ( water pump, brakes, fuel pump, bearings, body seals,) etc for 78-79 620 are all the same part numbers!

An AC truck will also have a shallow glove box to fit the ac up behind the dash.

Sweet! That was my biggest issue. So my window seals for the door are pretty toast. And recommendations for brand and where to get them?

Which seals are you referring to?  The ones that go around the top side of the glass in the channel of the door frame, or the ones that are down at the bottom of the glass where the glass rolls down into the door itself?

I'm in a similar state.  Mine are dried out and allow the window to rattle in an out depending on the bumps, wind pressure at speed, etc.  The only thing that I've seen for replacing are parts from Thailand, but they take forever to get here. 😒

Yeah mine does the same thing. And damn that's what I was afraid of.  I'll just deal with it for now. But I'm having another startup issue. Surprise surprise I know. When I go to start my truck usually in the morning but its random. It wont start. No crank, nothing. But I hook my jump box up to it it tries to start. My starter cranks for a second and then stops. Could my ignition solenoid or switch be bad? It is frustrating because it will be fine for a few days and then something else happens. Any ideas? Keep in mind if checked all the connections to the alternator, battery and starter which I replaced of course. So what could it be? I'll try to get a video tomorrow.  Do you guys think I have a draw somewhere?
