George, my advice from the very beginning still holds....Concentrate first on
designing the Bellhousing in conjunction to your E4D PSRU, and MAKE
PROVISIONS for the actual Bellhousing portion to be ADAPTED to Tracy's PSRU
or any other for that matter via means of a TRANSITION PLATE....This is the
best way that  I know of to make it cheaper, (by increasing the production
runs) and NEXT tackle the cats and dogs for further reductions, (Nitpick-it
to death)....This will yield your largest client market including those who
want to experiment themselves with their own PSRU designs.....Hell right now
there are a lot of us out here with a HEAVY Mazda transmission Bellhousing on
the shelf, waiting on future transitioning to the future best PSRU available
at that time, and I'm sure it's ditto DownUnder...No???

So IF I'm understanding you correctly, is this what you're trying to do right
now??...........If so take your time on it, now that you know that the actual
practical doesn't take that long......But please include a side and front
view sketch for us to critique effectively.

You would be surprised on how many persons would adopt to it period, by sheer
ingenuity :)
