[Flat Ernie]

When I was working on mine a long time ago, I actually acquired a 33/34 torque-tube and driveshaft. My understanding is that it would all bolt up to the later rear, but would need the oil drain hole drilled or aligned...

Unfortunately, a couple of military moves, then a bunch of life got in the way. My old '40 is in storage and hasn't run in a few years. I'm working on getting into a new place here in the new year and hopefully consolidating all my stuff in one spot. Maybe then I can work through my projects and get back to the '40...
