I worked on the prototype of the new redrive plate
today. The first picture is the set up on the drill
press for match drilling all the holes. The thing
in the center is the machined aluminum pilot that holds the old
plate (Tracy's redrive plate) on top, in alignment with 
the new plate on the bottom.

Once I drilled the outer 10 mm bolt holes I filled them
with short 10 mm bolt shanks to further keep everything
aligned while I drilled all the 1/4 inch holes.

In the second picture the new plate is up side down
with the machined pilot lying loose and most of the holes drilled
except for the starter.

BTW if you do this be sure you pilot on the oil seal bore.
The clearance hole for the input shaft is not necessarily
concentric with the oil seal bore.
