HELP!!! At the bottom, the rear glass in the hardtop on my '85 380sl appears to just float about 3/16 inch in front of the exterior bottom trim and 1/4 inch behind and above the car body. It (or the rear trim piece) rattles noisily every time the car goes over a little bump. Any ideas on whether there is supposed to be any support for the rear glass at the bottom or how I might be able to stop the rattle? I have temporarily wedged a hard rubber shim between the glass bottom and the car on the inside, and this stops the rattle, but may create too much tension in the glass leading to breakage.
