     Paul,

     Sorry I can't let this go I need the information !

     Using these calculations and your own,  the Ford planetary calculates out at 2.85:1  and
     1.85:1(reverse rotation). Where the hell the 2.17 comes in I don't know - it has been
     suggested that there are different teethed (in numbers) planetary. There is quite
     obviously something I'm not seeing.

Yes the 2.17 set used by both Ross and Tracy are different than the 2.85 set. Both sun gear 
and pinion gears are a different diameter.
