If the 4ZE1 to T5 bell worked for you, I wonder how viable the 4ZE1 to "auto used behind early Troopers" tranny is as a blank for the same purpose. I already have one of those laying around for another potential tranny swap down the road.
What does the backside of that bellhosuing look like? What you need is some sort of index by which you can center the transmission relative to the bell. The T5 housing has a large circular hole bored on center, which makes it easy... without that, you might need to indicate the bolt holes and claculate the center relative to a transmission housing (not impossible, but beyond my capabilities).
If you reduce the bellhousing down to its most simple function, it exists to hold the transmission body in parallel relative to the engine block, centered around the in-line axis of the transmission input shaft and the engine crankshaft. It also contains a clutch, fork, and some other stuff, but ignore those for the moment. <img src="/forums/images/graemlins/pfft.gif" alt="" /> You're essentially managing two bolt interfaces, which keep the engine and bellhousing aligned and the transmission and bellhousing inline. If you start with a bellhousing that bolts to the engine, you're halfway home... maybe more, since you the backside of the bellhousing is likely parallel to the front. The trick is figuring out tranny input shaft centerline and getting it inline with the crankshaft centerline ... this is a billion times easier if your bellhousing has a concentric circle (relative to the tranny input) available for reference.
