Ok so I wanna get the parts together I need to do a disc swap on my 14 bolt...but have a few questions...the info I have found has been from the Azkickin offroads website. -Parts Needed: 1971-78 GM 1/2 ton calipers or 1976-78 Cadillac Eldorado rear calipers, 1971-87 GM 3/4 ton 4x4 rotors, hoses, miscellaneous hardware. ok so can I just use any 1/2 ton calipers?? 2 wheel drive ones too?? or just 4x4? also if it is only 4x4 then what about calipers off a 89 or 82 blazer will they work>? the info I have says 71-78 thats a pretty small range is that actually correct? or just for "their conversion?" also what about E-brake cable? how does that work out? since the fronts arnt set up for an ebrake...anyways any info provided would be AWESOME!!
