Rears are next, didn't have much to start with, so lots of part #'s. Here's what I used:

Rotors - 03 Cobra Mustang, Duralast 54036 x2 $80, bolt holes are too small, so you'll have to open them up for it to sit flat.

Calipers - 01 Jag S-Type, similar to mustang, but more available. Pick and pull $20.

Hoses - 01 Camero outer's, Duralast 78537 x2 $24 (Metric Bubble flare ends)

Brake line -M10-1, 4 ft $7. To replace from center hose to disk hoses, no luck making bubble flares here, easier and cheaper to buy the dang line and redo center hose flares.
