HELP! 11.75" Disc Conversion - Bearings, Seals Etc

The Dr. Diff components say that they are slider type brackets, and I presume that's better than pin type, and I should go with the slider type brackets. That means that I'll need to make sure I buy slider type calipers (or are all calipers the same)? Are the calipers for the 11" rotors the exact same ones for the 11.75" calipers? I presume so but am not sure.
When ordering my parts, I need to give a particular car...so it's 74 Dart for my upper control arm bushings and ball joints, but 78 Cordoba for everything else?
Happy Thanksgiving, everybody!
When ordering parts,yes. As far as calipers go, for the type, and for all cars that are't A-bodies yes. The slider calipers for '73-'75 A-bodies are only 2.59" piston, the '76 A's &
all FMJ.B etc. sliders are 2.75" pistons......which are what you want. Some prefer the pin-type for less friction/free pad motion, but they all work.
