Dave,
 
    J= ust talked to the "ACT" flywheel manuf. and the 13.8 lb and 9.8 lb flywheels are identi= cal
(same ring gear_125 teeth) except for extra mill= work to take 2 lbs of the 9.8 lb version......
    If you happen to have th= e starter flange to gear teeth measurement handy please send it
to me as I am doing most of this 55 miles from m= y hangar/shop and I do not have the RD1X
starter with me at the moment..................W= ill compare the Turbo starter with your  starters
measurements.............By the way rotation on = all these starters is the same.............I still am
about 99.9% sure that the 9.8 lb flywheel can ha= ve at least 2 more lbs removed from the
clutch friction surface without hurting structur= al integrity for our use.............IMHO
 
Thanks,
  
Kelly Troyer

Great, I have the flange-to-gear teeth measurement on the current star= ter, to compare to the turbo starter when it comes in.  The other thin= g you will have to check is the direction of rotation.  Another soluti= on is to mill down the adapter plate and start flange to get it to stick ou= t another 0.37.  Could probably get away with 0.17 on each for a total= of 0.34.
