68 gmc 3500 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My Alter Ego · 04-14-2014, 03:49 PM

Just become the new owner of a 68 GMC 1 ton flatbed and am curious about the interchangeability of suspension parts. The truck has 4 wheel drums and I would prefer to have front disc brakes and maintain the 8 lug pattern. I presume the 72 front discs would be a direct bolt on, but wonder if there are later models that would do so as well. Also, I would like to swap out the rearend and presume that 69-72 would also be a direct bolt on, but, again, wonder if there are later models that would do so as well. Any and all assistance would be greatly appreciated. Thanks in advance.

I plan on doing a 73 up swap on my 1970. From what I understand it's easier just to put the entire new front end underneath it, crossmember and all. That is my plan anyway. I'll let you know how it works out when I get to it.

Yes,you can swap the entire assembly from a later model truck...at least through the '91 R3500s.
