Am I Crazy For This Idea?

Small upper ball joint 73's are very unusual. Very, very unusual.
Ball joint adapters from DrDiff solve the problem if you have them.
Lower ball joint is the same for all 73-76 A's, disc or drum.
F's are bent bar cars. You wont be able to use any suspension parts on an A body. Control arms off the F will not work.
Spindles, rotors, calipers, caliper brackets, prop valve, dust shields, soft lines, etc. grab em all.
If your going to get new/reman calipers get them for an 80 F body. Better positioning of bleeder/inlet.
Rear could be a 7.25 or an 8.25. 8,.25 is a 3" axle tube, 7.25 is 2.5". They were pretty much all 10"x2-1/2" brakes. HD had finned drums.
Use the schumacher conversion mounts. They are very nice pieces. I have a set in my Demon and the fit is excellent.
