I'll have to spend some time looking around at the random parts I have around here - I've got a sm465, a 208c, the Jeep's original T10/d20 combo - I would think at some point there was a six hole round passenger case made, but if not hopefully there is a case that I can swap the guts around in. I would prefer not to Frankenstein a tranny.
I really like the doubler idea - hadn't even thought of that. The Jeep has narrow frame rails, so the size of that might end up being an issue.
That behemoth strongbox thing is pretty awesome as well - I wasn't aware of there existence. Anyone know of an overdrive box like that in a similar price range?
