I want to put disc brakes on my 1971 GTX, I have purchased a pair of 73-76 A-body spindles with the smaller 10.87" unicast rotors, with the slider caliper adaptors. The sliders adaptors look very similar to the ones on my old 1983 Diplomat. I need calipers and flex hoses, should I order calipers for an 83 Diplomat ? I have been told the 73-76 A-body flex hoses are the ones to use ? I want to mount the calipers in the front, I am not using a sway bar. The car has new lower ball joints on the drum set up, can I re use them with the disc swap ? THANKS for your help / input.

Have you read the famous MA article?

THANKS, I can use the 73-76 A-body flex hose and re use my lower ball joints. Still not sure on which year/model of slider calipers to order ?
