How would the weight compare to Tracy's RD plate, spacers and bolts?
I'd like to have my starter farther forward (pusher) to help with W&B
issues if there were no total weight penalty.

The weight for a stock high pressure die cast bell housing is
several pounds lighter than Tracy set up as I recall counting
spacers and the long 10 mm bolts. Aluminum weighs .1 pound
per cubic inch so a 12 by 12 1/2 inch plate would weigh
7.2 pounds not counting holes. My guess is the total set up
is 8.5 to 9 pounds. I have one at the hangar but I am not there.

The weight of the stock 2nd gen manual TX bell housing is about
7.5 pounds. If you cut a hole in it so Tracy PSRU fits that
should reduce the weight by .75 to one pound. The starter is
on the PSRU side. If you want a side mount starter ahead of
the PSRU you meed to find a 3rd gen auto TX bell housing like
Bulent has. I don't know the weight of that one.

Paul, there are few things to consider with setup like my engine.
You need a longer drive shaft and Tracy  said he will not make them.
The starter engages from behind the flywheel and the teeth on the flywheel are cut to accommodate that.
If you use the correct flywheel (Cosmo/20B) Tracy's dampener plate will not match the holes on the flywheel, so adapter plate is needed. There are few other smaller things to consider.

The trick is to partially mount Tracy psru in the bell housing.
I guess you were not on here when we discussed that. Here are
a few 3D's. This is what Ian did.
