rear disc brakes on 8 3/4

72bluNblu ,
very good Point. Didn't know about that off set. but can't be that much. It is working this way since 3 years. But you are right. I saw that the linings are not centered in the drums. One reason more to Change it to discs. :)
ok, got yukon BBP axles and green bearings already.

mguner,
you did that swap? Parts list, sources etc?

74DartSwinger360,
did you ask right stuff where to buy pads and discs?

Yeah I posted it here a few times. I can't remember what brake lines I used but they were a common part as well. Speedway motors has braided line kits and banjo fittings along with the weld on caliper brackets and line mount tabs. The Intrepid calipers are a perfect fit to the loaded GM metrics with E-brake and are tight on the 8.75 axle flange which may require just a little taken off the flange or the inside of the rotor hat. If your studs have much of a shoulder you may have to counter bore the lug holes in the rotor too (5/8 or 9/16 bit).
