 If you can spin bell housings Ed we will beat a path to your door.
 We can use them for the PSRU.

That sounds like more than I could deal with. There are bell housings
available that will work with late style cast iron [end housings]. 
The RX-4 and I think the  pickup truck will work.
If I were desperate I would use a rear cast iron [end housing] from an early engine like an
RX-2 or RX-3 and use an early bell housing from one of those cars. Or just
stand a thick plate off the rear cast iron with spacers like Tracy's layout.

Well that is what we are doing now but weight wise it is a bit heavy.
The four inch long bolts and three inch spacer them selves are a lot of the weight.
Looks wise or cosmetics it is less than pretty.

Most Mazda Bell housing are too long for Tracy input shaft as well.
