Clean pair of backing plates with custom machined pieces for self energizing conversion. I took measurements off a set of Lincoln Bendix style plates and machined steel pieces that when welded in will position the adjustable anchor pin in the correct spot. Was going to convert these to be self energizing but have since found 2 sets of original Lincoln brakes. You will still need to mount the wheel cylinders and clearance the lower part of the backing plate but this takes all the guess work out of the anchor pin location. These later plates also have the pads for the shoes to ride against making them the best for converting to Bendix style operation. $150 obo plus shipping
