Converting '67 Chevy C20 Power Brakes to '71 GMC Disk

[DJ_Baar]

Thanks for add to group.
I just picked up a 1967 Chevy C20 LB Camper Special. Only thing not original is 350 replaced 327. Seller provided most everything from '71 GMC front disk brakes he got, (told me same 3/4 ton 8 lug, but 5/8" lugs vice 1/2" and wheels still fit). Anyone do this conversion before or similar & have some constructive advice? And any difference with brake parts other than number of lugs & pattern between C20 & C10? I didn't see any difference in parts catalogs I looked at.
