I did find that the SL500 (3 web) will interchange with the SL600 (4 web. I was able to figure that out based on the fact that both transmissions have the same output shaft part numbers.

I will order an SL500 flange on Monday.

I have been looking closely into Megasquirt for this engine and I have come to the conclusion that I can replace my electronic Throttle actuators with Ford Mustang 70mm throttle bodies, available anywhere for ~ $150 each I should be able to get this to work with wide band O2 sensors without MAF. If I just sold one of my throttle actuators it would pay for the whole system. The only real problem with this is that if I dont hook up the original system, I will not ever be able to scane the CAN bus for the MB propritry codes.
