I have a 90 k2500 with a 4 speed manual trans mission, i broke a pin that holds the shifter handle from spining around, i can shift in to every gear fine but the pin that stops the shifter from spining broke. i took the the dash panel off and the boot and got it down to the transmission, all i can see is 2 roll pins in the side of the trans that look like they need to come out but im not sure ware to go from here
