Congratulations on joining the Air force.

I have always wanted about a 3.55 final drive ratio to help fuel economy.
I also wanted to see if a RX8 diff would fit (4.77:1 and IRS).

I do know that the mazda 929 differentials bolt into the turbo II differentials (learned from Ray on v8rx7forum.com) they only have a 3.73, 3.90 and 4.10 ratio available though.
