ok guys a few more questions. my tranny needs a rebuild for sure. but i want an ls 5th. is it worth doing new synchros and the ls 5th, or would it be cheaper to find a different tranny with close to the same setup? what tranny would be ideal?

im not going turbo anymore, im going n/a, but i still want a lower cruising rpm in 5th for better gas mileage. what should i do?
