donor truck year compatibilty

[Jamminjohn]

I have recently bought a project truck that is missing quite a few parts.

I was thinking of buying a donor truck and just taking the parts from it.

I honestly dont know what I have.
I know I have a 70 cab with a 67 front clip.
I also am pretty sure its a long bed(missing bed)
I bought it off a member here and he hasn't responded to my emails or texts
asking for clarification. I have searched his posts and it looks like it could
either be a 67 or 68 c10 or c20. The front and rear ends both have been updated to 5 lug and it has airbags.


My question is, Can I buy any 67-72 longbed c10 or c20 and use the parts
interchangeably?

thanks,
John

It depends on what you want to make the truck into. Beds 67-72 are all interchangeable, you can bolt any front clip onto any cab but there are slight differences between the cabs throughout the years. Chevy fenders are the same 67-68 and 69-72 but GMC is different. If you have the vin you should be able to run it to see what year the truck is. I would do that and then go from there. Also if it has a glovebox door that matches the vin in the door jamb that should help a lot. Hope this helps

I basically need the bed ,windows, brake lines, fuel lines, hood hinges, windshield ,
possibly the core Support .

Are those interchangeable?

Yes, all of those should be fine. I believe the core supports changed from 67-68 to 69-72 but I could be wrong. A good way to check compatibility is look in a parts catalog like LMC and see how they divide parts by the years.

LMC's catalog is pretty good for a reference. We use it often when assembling trucks from different donors.

The core support for the 67-68 trucks are different than 70-72. The fenders for Chevy 67-68 are the same, except the 67 does not have side markers. The a '67 bed will fit 67-72 trucks but does not have side markers.

My son has a '71 lwb truck with a '67 front clip and bed.

I have disc brakes in the front and drum in back.
Can I use the original brake lines?

[Jamminjohn]

I am getting conflicting information.
I have a truck and car shop catalog that shows 67-68 match pretty much everything.
But the LMC online catalog shows matching part numbers for 67 and then 68-69.

You are in the same situation as many of us. The '67 swb stepper that we built has parts from at least 7 different years of trucks, so if I need to buy a part I have to remember what year that part came from.

Often it is best to take a part to the store if you are getting a new one to match it.

O'Rielly Auto Parts website has a compatability section on parts that helps tell what parts will fit what vehicles.

If you post a picture of what part you have on here many people are able to tell you what year and vehicle it came from.

Are you referring to the front fenders? 67 and 68 fenders are the same with the exception of the marker light. You said your truck is a 70 which means you could use front fenders from 69-72 and they will all work with either a 69-70 grill or a 71-2 grill. As far as the brake lines, I'm not sure the differences but I do know that 71-2 trucks had disc front drum rear. I would say if you could find a nice 71-2 lwb truck for a parts truck you'd be in the clear.
