On the retracts you need to drill and tap the mounts this mounts are G10 fiber plates so i bought a tap set in harbor freight to do this you will need a 4m .7 pitch tap also you will need to do a small notch in the plate so the air line can go in when installing the retract i made this notch 7/8 inch from former
