Thanks for the input, Stude. Yes, 5th gear is .68 but the rearend is a 9". I don't think 3.73 is an option for 9". only 8.8. For 9" I think it goes 3.50, 3.70, 3.75, 3.89 and up. I know a lot of later model Mustangs run 3.73s with the T-5 but they're usually running 26" tires. Since my tires are 28", the 3.89 would probably accomplish the same thing.
