Frame swap?

65Matt · 05-10-2008, 02:00 PM

I have a 65 C10 2wd and am looking to swap to a 4wd frame. I found a 1983 K20 suburban donor but unsure of total length of it. The info I found said the wheelbases were almost the same and I know I'll have to fabricate the mounts. What do you think? Also I went to go rent a tractor on a trailer and the guy told me I needed at least a 3/4 ton to pull it (that's why I found the K20). What's the difference between 1/2 and 3/4 and is it really necessary to go bigger? You guys are great! Thanks, Matt.

Axles front and rear, ball joints, control arms and spindles are all heavier to withstand more weight.

don't think you will have much luck trying to get an 83 frame under a 65 truck. The rear kick-up is completly different. Getting the radiator core support to fit so that all the fenders, hood, etc etc, will line up properly would also be very difficult.

73-87 1/2 ton and 3/4 frame are the same, only one ton is bigger. the rear spring length is 52" on 1/2 and 3/4 ton unless vehicle was optioned with C6P heavy duty chassis 8600 GVW. In that case you got 56" long rear springs, otherwise chassis still the same. You can see both sets of holes on any chassis. 1/2 ton and 3/4 ton have the same front end except 6 lug or 8 lug hubs, rotors, calipers and brackets. 1/2 and 3/4 ton used same transfer cases depedent on transmission option.
