1 ton compatability??? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

amstaff · 09-13-2013, 08:42 PM

It's been a long, long time since I have posted! I just found a '68 GMC one ton dually... Has low miles, is pretty solid, and comes with its original flatbed. Owner believes it is a 283, but when I did a little research I found that they stopped using them in '67. Possibly a 307?

Anyway, are parts for this '68 dually compatible with say a '68 3/4 ton? I understand suspension would not be compatible... but is there anything else?

Any help would be great! This could be a great farm truck/ hay truck.

You should be able to replace/upgrade everything on that truck with parts up into the late 80s.

It could be a 307 or possibly a 327. The frame is different and the rear is narrower. I;m sure you now the brakes and suspension is different,but the rest is interchangeable with lighter trucks. The sheet metal and everything within is the same

Thanks for the info! I will take a better look at it next week.

I didn't look at the badging on the fenders... what are the GMC one-tons designated as??? I know the Chevy is a C30... same for GMC??
