Paul,
Do you know of anyone who have successfully made an adapter plate for Tracy's redrive with the starter at the 3 o'clock position???  I've found myself in a bind trying to make the original adapter plate work with my "already purchased" motor mount, but Tracy does not provide adapter plates with the starter in alternative positions.  Would you suggest any other redrives if resolving this clearance problem is not possible?

Here is a sequence of pictures on how I did it.
I made a plug on the lathe to transfer punch the center of the starter
hole rotated CCW from the 6 o'clock position to the 3 o'clock
position using Tracy's plate as a pattern. Then I used a hole saw 
to rough cut the starter pilot hole. Then a boring
head to finish bore the starter hole. Then I used the starter
itself to match drill the starter mounting bolt holes in the new 
motor plate.
