I presume you're talking about the single-switch arrangement, and the
screw you're talking about is (used to be?) a small hex socket
protruding upward.

I'm sorry to tell you that's not a screw, it's part of the cam and
it's made of aluminum.  Unfortunately VW also made the plate it
passes through out of aluminum, so the two parts corrode together at
the hole and there goes the aluminum hex, it can't stand up to the
steel hex key.

I know Ken Wilford carries these assemblies.

Yours,
