door glass help!!

I have removed mine numerous times without removing the vent window. It can be done.
$120
Be careful not to damage those plastic pieces that are attached to the glass that are in the vent window channel. The repro ones are $120.

Have you removed this rubber piece in vent window frame?
There is little screw in there holding it... that might help you. You have to take the rubber cover pieces off also on the doors end near the door handle.
