F,M,J Body Brakes fit on an A-Body?

Im doing the exact same thing on my 66. 87 gran fury spindles, hubs, new seals and bearings, caliper brackets, prop valve, (im using the rear axle as well, 11x2.5 drums, so the system is matched to the valve) 74 scamp upper arms, offset bushings, new eccentric bolts, C-body tie rod ends and adjuster sleeves, suprisingly they are literally half the price as early-a tie rods and sleeves, have the same exact taper, plus the C-body ones are bigger threads, 11/16 compared to 5/8. 73-76 lower ball joints, grade 8 bolts with castellated nuts and cotter pin holes drilled in the bolts to bolt together the M-body spindle to the 73-76 lower ball joint, steel piston calipers, 76 volare brake lines, 70-74 E or B body manual disc brake master cylinder, and im sure a bunch of other stuff....but thats what i have sofar!
