In the last stages of removing the transfer box from my GPW. Now to drop the transfer box out I need to remove both the small shifters for the Hi/Lo and 4WD. In order to do that I need to get the pin out that holds the bar in place which the shifters attach to. What sort of pin is it, apart from being Bl***y awkward to get to. Is it a hex screw, slot,cross type? Any pointers gratefully received.
