69.85.158.8
The Gama goat used the same transmission as the 40's-early 50's era Chev/Gmc stubnose cabovers only internals were updated to more heavy duty usage behind the GMC diesel>The topshift cover is probably 40's design as it fit the bill for remote shifting capability.But even looking for a cabover shifter will be just about as allusive as a Goat shifter.That's why the post to see if anyone else had crossed these waters and what they used.I believe the shifter uses a single shift rod for gear shifting and a cable for the selector to determine what gears are shifted but I'm guessing.
