60-66 to 73-87 Transfer... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

GMC-V6 · 09-17-2023, 11:06 AM

I have 62 GMC dually... ideally I'd like to transfer its power train and body over to a 73+ frame.. Cab n chassis to Cab n chassis.

Parts of like to transfer:
Cab.
Front clip.
Engine.
Transmission.
Rear end.

If possible to swap over I'd be looking for a 2wd with a 60 inch cab to axle.

There's a couple threads, and a rather thorough one where it's discouraged.
One is a VIN matter, but depending your State you live in, it may not matter.
The other reason is the shape of the 73+ frames. I guess they bump up under the cab so it makes the whole truck sit higher on the frame. Probably look fine for a 4x4.
.
It's been said that the 73+ suburbans don't have this bump up and our trucks could potentially sit correctly, but I don't know if anyone has ever confirmed.
.
The most well known thread on this topic might be linked in the FAQ's.

Is your frame bad? Why do you want to switch them?

**cwcarpenter98** · 09-18-2023, 10:45 PM

If your original frame isn't bad, your best course of action is to put the front suspension and rear axle from the squarebody on your 62 frame

On a square body truck frame you will end up with a 3" body lift unless you do some serious modifications

I was going to do the front end swap but looking closer my 62 frame is all beat up and starting to have soft spots... So I'd being saving a dying frame.. So I was trying to find out what I'd need to get for a frame to slide under the truck.

I don't want a square body powertrain I want the 62s powertrain fan blade to rear end.
So figured if the front swaps why not the frames😂

Apparently that's not easily done shame they don't make much for dually parts.
So I need a 60 inch cab to axle cab n chassis frame I can put the GMC V6/4spd/Diff into.

You could try to find another 60-62 frame, a 63-66 would work but the bed mounts won't line up and the frame horns where the bumper mounts will be different. Then 67-72 with the same mods needed with the 63-66 frame.

I need a dual rear wheel cab n chassis frame that is 60" cab to axle.
