Ok I know you need callipers from a 71-78 3/4ton(D44 CALLIPERS)Can you use callipers from a 79-87 3/4ton(8LUG 10BOLT)? I though they were the same except for the bango bolt size Will it make any differance? And does anyone know what brake like you can use from the hardlines to the callipers other then the A-TRON hoses(im starting to run out of $$$) /forums/images/graemlins/1zhelp.gif
