When it comes to dropping a transaxle its all the same concept. Your just gonna have to use a little ingenuity to make it fit your frame. There is no step by step for your transaxle, your frame, your motor etc. If by a long shot there is, that driver may run a different length track than you or prefer a little different set up.

Gotta figure out what ratio you are looking to get to so you know track size including straight length gotta know built motor or stock, tire size you wanna run and what the output ratio is of your transaxle in race gear with all that these guys should be able to help

I got to the dropping part can't get no easier. What I don't under stand is what pulley to run on top and bottom of jack shaft to be the same as a 8" on motor and 3 1/2" on rear without a jack shaft.

If you run the same size pullies on the jackshaft (top and bottom) it does not overdrive or underdrive the transaxle pulley, so the ratio stays the same. You could run a 4", a 6" or even a 12" on the jackshaft. If they are both the same, it's 1:1 on the jackshaft, just like it wasnt there...

.  So if I run 8" on motor 4" on top and bottom of jackshaft, and 3 1/2" on transaxle it will work fine?
