Try this on your bad windshield first. A little crude perhaps, but I have not
lost a windshield or window yet. Bruce at Tassi Inc. in Colma showed be a
quick and dirty way to pop-out windows and windshields (for early models
without glue in the channel).

Turn your back to the subject windshield. Kick backwards firmly with your
rubber soled heel at the edges of the glass. Once the seals are popped. You
just pull the windshield out.

This procedure is not for the faint at heart.
