Selling a new in box Wilwood Dynapro rear disc conversion with built in parking brake. This works on 63-87 C10 axles that have 5 lug axles. The rotors are drilled and slotted, calipers are anodized black. The rotor is 11" in diameter so they are compatible with wheels as small as 14". Calipers have 4 pistons. Wilwood part number is 140-11385-D Asking $650 plus shipping.
This particular setup is brand new still in the box. The pictures are of the same kit but I installed in on a truck.
