Re: Help! 67 gmc k20 71 k20 cab frame mount difference

Rad support hole size should be the only difference 68 has a smaller hole then the 69 72 trucks

Prothane had a disclaimer in there cab mount kits about this to open the hole up wider or cut the collar off the body mounts

Cab mounts themselves should be in the same actual place as the cab is the same 67 72 c10 c20 c30 k10 k20
K30 would have been a napco or diy thing

Put your cab and front clip on and test fit to the frame
