Coupler pin steering box help please.

Either a flat pin like Alaskan Ta or a true pin punch. They are sized for the diameter of the pin and instead of being flat are flat with a small ball shape on the end that fits into the hole of the pin. Either way works but they are tough. Have someone hold your steering wheel tight while hitting. The wheel tend to move since the pin is off set. Good luck and the longer the better.
