Cool, i hear what you are saying on just getting it to run and stop. Sometimes M body spindles and parts pop up on fabo from time to time. Currently i have these turned rotors with bearings, and a sandblasted clean set of M body caliper mounts i wont be using. Shipping a set of used and turned rotors is however cost prohibitive. At that that point your better off finding em new if you had to pay shipping.
However, I wouldent wait too long to head this way for a set of these even if to put aside for later use, when scrap prices go up they will clear out most of it, and smash it down, and it will be gone.
Your total cost for this stuff would be between $100 and $150. Borrow a buddies fuel sipper car to get here cheaply. Calipers rebuild cheaply. The stock phenolic pistons are problematic, get stainless steel pistons. Other than the 79 cordoba big 12" rotors and cordoba caliper brackets all of which bolt right onto M body spindles, heres the breakdown on new rockauto parts all on closeout i bought to do my sons front discs on his 69 cuda. Incidentally he is only 5 now, i am rounding up everything now for that future project while i can still get it cheaply.
84 Diplomat steel caliper pistons (bendix) $3.39 ea
84 Diplomat caliper rebuild seal kit $1.99 ea
84 Diplomat wheel dust seals (SKF) $1.25 ea
84 Diplomat brake pads (raybestos) $15.25
84 diplomat master cylinder $12.29
74 Dart front brakelines $9.96 each
Again those brakes wont go bad sitting in the corner of my shop for the next 10 years, neither will those new parts packaged up in their boxes to rebuild them. If you have the 10" drums the master cylinder you have should work for the M body discs, since its designed for disc and drum application.
