I emailed Tremec, they said this trans uses the same bell housing as the TKO (makes sense that they would design it like that). One of these would be pretty awesome in my 67 Coronet.
I'd guess there would still be some cutting/welding to get it all mounted and I've got an Auto car so I'd have to do pedals and all that stuff, would want to fab up a master/slave hyd setup for the clutch I guess. Seems like alot of work and research...
