Thanks for the tips! And now another subject, ... info that I received from GM rep Dan Garrett at the museum in October:
If you break a windshield, front or rear, it is a major operation to replace. They are glued in and bits and pieces remaining in the rubber seal have to be picked out one by one.
If the rear is broken, replacing the hatch assembly to which the glass is mounted may be the best option. If done of course it will have to be painted. Broken windshields are often hard to avoid ... Insurance Co's will go nuts when they hear about this.
