anyone have any idea how much the axles walk? (Ill check my manual for a spec) If so I can compare that spec to the Chevys. I hate using Chevy stuff since Im not familiar with it but I know a few guys that use the caty calipers for the rear conversions on Mustangs and they are happy with them even though the Ford 8.8 uses C clip axles. I am also very happy with the SN 95 rear disc all around and The E brake holds better than the cable did with less effort. They are not real expensive but they use a solid non vented rotor (thiner than an vented) That would be hard to convert. They require a special tool to spin and press them back in durring brake changes but its cheap.
