If only he lived in CA, there's a guy selling a tag with that on it.

I don't know the answer to this for certain either, but I would think that the same gear box with two different input shafts would have two different part numbers or model numbers since it's a pretty important difference. I'll try to contact more people to see if some one who as seen it with their own eyes can remember the spline count. My friend with the Z4M race car is certain that it's different from the M3, but can't recall exact spline count. Maybe he'll have an old clutch disk laying around....

They do have different part numbers, only the base designation is the same, the extended designation still isn't.

Okay, I C. Well, if OP does a clutch job, maybe that will be the first eye-witness account....
