Got my answer to the window rattling last night. I drove the commute home with the top down and when I got home, I put it up. When I go out of the car, I noticed the rear window had separated from the top along the bottom edge of the opening. OK, now what?
I got busy and did some research and found a few threads on other sites about reattaching the glass rear window to convertible tops. I found a few people who had good results from 3M Windo-Weld, a two part system just for glass. I ordered some and will report results next week.
