95 Cherokee rear discs (pics)

every rear brake part, and I mean every rear brake part is from the donor vehicle which in my case was a 1995 Jeep Gran Cherokee 4WD. Even the Cherokee brake hoses and lines fits.
you are talking about the rear setup right?

exactly. rear brakes. rotors, lines, bads shouldn't be a problem. But spash shield, mounting bracket, calipers will be.
How does the emergency brake work? Mechanical?

What else is needed for an 8 3/4 axle (bbp)?
