I'm looking into buying an 87 k10. The only issue is that it's automatic and I would really like to swap it to a manual. It has a 305 in it. Anyone have an experience with how hard of a trans swap that is? i know the normal stuff like needing to get a master and slave in and adding the 3rd pedal and cutting the floor to make room for the shifter. But what about any necessary adapters? special pilot bearing or new flywheel ect
