Diana - I have NFI, however discokid runs a TF727 in his race truck, so may know (he is probably out looking for his stolen trailer... ).

Also, the IH Scout used a TF727, so most of the scout guys know a lot about them (e.g. try pirate4x4.com).

There have also been some discussions on outerlimits about the best auto options to go in a (rover)V8/auto/LT230 drivetrain.
