73mm front calipers, SVO Master Cylinder, 3-2 conversion, adjustable prop valve, and e-brake cables.
Honestly, i wouldn't waste time with a Mark 7 rear setup unless it's the Varga type off a 91-92. It's old, and TOO much rear brake for a Fox Mustang. Youll have issues with the rear locking up before the fronts, and the only MC that works well with it is the SVO MC as long as you use the SVO 73mm front calipers. This is why it's a seldom used rear brake setup....also, it pushes the rear wheels out 1.25" EACH side...so you need some wheels with DEEP backspacing and offset.
