Ahhhh....
OK another question then. It looks like the mystery part I posted appears to be for the rear quarter window,not the door window! In the link you posted on page 6-30, Fig.9, part #9 looks like the part in my pic. I don't have the car here in front of me now to verify,but maybe that explains why we could not figure out where this went! DUH!
Thanks for that link and the reply!
BTW,I noticed I posted this question in the wrong section,I had just reposted it in the "bodyshop" area before I saw your reply.
