Darin, why limit yourself to only the gear ratios afforded by the transmission you already have?

It would only be slightly more difficult to just pick a ratio you'd like to have, find out what transmission/transaxles have shaft spacing like yours, and then dig through and flip the gear ratios in those transmissions to find the ratio closest to your "ideal" ratio (that you created from some thought in your head.)

I can understand if you don't want to do this, but I don't see why you should be limited to only selecting a gear ratio based on what you already know will work, when you could easily (maybe?) find out about other options as well.

Especially if you have access to a salvage yard that will let you play around inside... you can pull covers and check gear spacing to your heart's content!
