the whole tin section where the parking lights set in is uniquly different from where a chevy is fairly streamlined around the hood latch to the parking lights a gmc has more of a customised frenched look to it, same with the 60-61 gmc to chevy apache hood,while the hood itself the same the whole front tin secton is uniquly different from a gmc to a chevy but as well the hood will fit with no problem, however there might be some problems with switching over from 61 and back to 62 and up from the shape of the hood itself but on that I am not sure.
