early a body fmj spindle & master cylinder choose . modification

87 Gran fury knuckles + discs, early 70s C-body tie rods inner and outer, and 73-76 balljoints are whats under my 66. I used a 73 charger manual master, with the 87 gran fury prop valve. if i were to ever do disc id probably get an adjustable prop valve combo all in one. Ive seen em somewhere before, i want to say inlinetube.com? Anyway. good luck!
