Is the rear end from a 91 Mark the same as mustang?

All 8.8 housings are the same. The diffence in length is in the axle length. With that said the diff in the 91 mustang and mark vii are both 28 spline traction loks. Gear ratios may be different as the mark vii came with 3.08 or 3.27. I believ the mustang came with 2.73 or 3.08.
