rear disc from grand cherokee on a 8 3/4

We put a stock 15" ralley wheel on it and it cleared fine, the 14 did not it hit the caliper. His car has front disc's so we used the existing proportioning valve and it seems to work okay.
We didn't have the e brake assembly to try it on so really don't know if it is a perfect fit or not. But it looks like it would fit.

Look at it this way J.R, now you have something to do besides watching Oprah !!!
