The upper mounting studs for the cross-shaft could possibly be larger for the later model arms if doing a truck to truck swap. I would measure/validate the studs on your '68 & compare them to the '83 upper arm shafts.
I've never messed w/an earlier C20; only 73-87 & later models. But, I have done enough 67-72's & 73-87 C10's to know things changed for the 73 models:
*The bushings on the 73-87 C20-C30 are still the same HD set-up like the earlier trucks.
*BJ's will be different between drum & disc set-ups.
*The later model arms will physically swap over but will require the rest of the package to be updated as well.
