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.
