Ive got a '72 3spd transfer case that has an extremely worn 2wd/4wd shift fork, causing my t-case to pop outta 4wd into 2wd while driving. I have a shift fork from a vaccum operated '67 3spd case that is the same dimension, but needs a hole drilled and tapped for set screw to fit in newer 3spd case. Anyone done this? Figure id give it a try. May give another option if people cant source a shift fork for their year of t-case.........or someone could sell me theyre fork for dirt cheap
