Anyone around happen to have one? They were primarily used in GMC 2 ton and up trucks '40s through '50s. They are a big trans with a different shift pattern than most with some good low gears and 5 speed overdrive. Clark made a few with overdrive options, the 207VO being the most with .87 over, the others at .80.
If you haven't already, you should ask this same question over on the oldGMCtrucks forum. Much more likely to find one there.
