This would be a great idea ...  although I don't think it needs to go
this far.  Here's my thoughts -

Dimensions on the needed bolts would be real good.

I don't think we need to worry about the dowel pin.  If the bolts
holding the transmission to the engine are tight, it will not
move around.  Remember, VW and 356 Porsche's held the entire engine
onto the transmission with 4 bolts.  Yeah, 4.  Thus, no offset
bushings either.  Remember, there's several cars already running
around like this.

A template for relieving the transmission bell housing would be OK,
When someone has the old transmission and the new one laying there
on the floor, a quick shot with a high speed grinder will certainly
do it.  It doesn't need real precision - as long as clearance is
created and they don't cut away too much.  If we had pictures of
that area of both bell housings it would probably suffice.

So ... when you convert your car, please take pictures of both
gearboxes, I'll put them in my transmission web pages.  Also,
please take pictures of the oil pump area and fittings.
