Im only using a single brake setup on the rear. In fact I just got the new backing plate complete kit for both sides for 110.00 the shoes were 60.00 so I bought the comp kit and I know all the parts are new for 40 more. the kit inc, plate, springs, anchors, adjuster, aluminum wheel cylinders and new shoes. no drum. Its gonna be faster to replace the whole unit than doing just the shoes. I was gonna convert to disks but price was tripled and I would have to get a free wheeling reverse solinoid.
