Antenna question

[dos tres]

I can't figure out how the antenna mounts on my car. I found it dangling in the fender well, and it appears that the previous owner replaced the fender with an aftermarket one. It looks like the antenna mounts somewhere in the door jamb? I can't find any holes to route it through from the inner fender well. I'm stumped. Anyone have closeup pics of how the antenna mounts? I can't find any via Google.

Perhaps this ETK/BMWFans diagram

Thanks Jeroen. There's an impression in the fender that looks like the square bit the antenna passes through in the pic. I'll bet that needs to be cut out and that square piece in the pic is a rubber seal that it passes through. Before I go through all that trouble, I might find some kid of aftermarket antenna I can just hide under the dash or something.

does anyone have the part number or the antenna itself as show in diagram item # 1?

I think the part number is 65211371264, but it's no longer available.
