get a reverse manual valvebody for the auto , then it shifts like a manual and you can't outrun one with a manual..BTY, you'll also have to change the shifter to a ratchet type...

You will need to remove the automatic bushing from the TT motor and install a pilot bushing for the manual trans.

You can use the NA manual transmission. You can stick with the NA flywheel and go to a clutch that will support the tq and hp of a TT, Southbend offers several that will work well.

You can also go to TT clutch/flywheel but you will need to grind a small amount of high spots on the inside of the bell housing to provide clearance for the larger diameter TT flywheel. You will also need to shim the starter out.

Hope this helps,Tim
