A leaf spring rear end as well as the Dana axle (GMC set up )could have been "special ordered" not a "regular available option" on Chevy's if the customer really wanted it, and a few did, especially on 3/4 tons when hauling a camper. Here is one. http://www.ebay.com/itm/1966-C20-V8-...p2047675.l2557 |
Thanks factorystock, that's by far the best supporting evidence I've found to date. Do you have any other examples you've seen saved, or any other information? Very interesting.
Like you said, it's probably a good idea to run through and list the types of suspension vs. model again.
AFAIK:
1960-1962 GMC = x-frame with torsion bars and rear coil springs
1960-1962 Chevrolet = same as GMC
1963-1966 Chevrolet = ladder frame and coil front and rear springs
1963-1966 GMC = ladder frame and front coils with rear leaf springs
(only applies to 2wd 1/2-3/4 ton trucks made in the US)
1 ton/C30/2500 (and up) trucks all had leaf springs on the back and 4x4's all had leaf springs all the way around.
Starting in 1968(?) you could order leaf springs as a standard RPO option on 1/2-3/4 ton 2wd Chevrolet trucks.
Apparently, you could also special order a Dana 60 GMC rear that came with leaf springs under a Chevrolet C20, at least in '66?
At least some plants in Canada seem to have built GMC's on Chevrolet frames?
