you do have to have uppers from a 73 up a body though.you can use disk spindles from a 73 up b, or f body,BUT,they are taller by about 1 inch,so its gonna throw your suspension geometry off a bit,unless you lower the ride height,then the geometry comes back to were it should be.If you keep the stock ride height in the front,go with a body spindles.You can still use bigger caliper adapters,and rotors from the bigger b cars(like cordobas)with the a body spindles,if you need more stopping power.Be sure you rob the prop valve for the discs off a disc car.You need a 8.25 out of a 73-up a body if you want the easy big bolt rear swap,all others will need to be narrowed,or rear wheels with more backspacing,and spring perches relocated to work.If you have the cash for new stuff,master power brakes has everything you need to do the front swap(so does stainless steel brakes) including the brake hoses,prop valve,upper control arms,rotors,calipers,etc
