OOPs!...looks like I had some HTML code embedded in my last message.

That VW part # I need is 01-10024.
(not 01-10024=20!)
 It is ,I think, a mirror for an 86-90 Jetta, but I would like to know for
sure. also would like to know what other vehicles it may be used on.
Any info, again, would be appreciated.
