Sunroof crank missing a piece>?

[DaN]

I finally picked up another sunroof crank at pick n pull,went to install it, but it wont crank the roof open. It just spins the shaft round and around without turning the gears. Can someone look at theirs and see if there is a metal insert that connects the shaft to the gear?

I don't see any parts on the realoem diagram.
I'm guessing the piece fell off while driving around for 2 years with no crank installed.

Thanks

I was lucky today, an e30 came to the dealer with a crank sunroof. I took the crank off and noted the piece I'm missing. It's a little insert that slots onto the shaft and has a little tit that engages on the gear.
Anyone have a parts car I could rob one off of?
