Instead of changing the trans flange, how about changing the drivshaft flange. I bought the 3 bolt flange for my 5 speed conversion from a old 320i driveshaft for $25. You going to have to shorten and rebalance the driveshaft anyway.
If your driveshaft has never been rebuilt, get it done during the shortening process. New u-joints and center bearing.
Bigger 320i guibo too.
