No idea man. Take it from first hand experience. The ZF6 is NOT fast. You have to row that girl through the gears. The fastest shifting on it is 3rd gear launch, 5th, 6th....
Guess I need more posts before I can pm HERES a link that should give you a good idea of whats going on
Midwest Trans sells a short throw shifter to shorten up the shifts
I doing this in a couple months and will more then likly do a write up too. Best thing to do is get a junker with everything in it you need. Other wise if you have time it can all be bought in peices.
