CPP 63-72 GM PU 3" Rear Heavy Duty C-Notch Inserts

Required on drops of 4" or more. We saw a need and filled it with this outstanding product. Made of 1/4" thick steel, our C-notch will provide more than enough support for the frame and installation does not require the bed to be removed. All hardware is included. Some modifications needed when used with coil-over kit.
