I am trying to piece together a Muncie HD 3 speed just as a project. Could use information if anyone has literature, shifter stick,rough looking original knob or cheap parts that cannot be used on a 4 speed. Here is a picture of the shift coin courtesy of my bestest buddy Wheelz
There is another stamped number on the tag under the bolt. Can see the factory yellow "M" or"W" stamped on the housing past the id tag, was cool to unearth beneath almost 50 years of grunge : ) I love detective work
