keith is right on in his recommendations, and he even took the time to bring me his extra spacers.

But even with the new spacers put in at the bottom of the panes, my back window has a gap of about 1/8" across the top--I filled the gap with silicone when I noticed it on a trip, will need to take the pane out and use taller spacers.

The operation is rather simple, just take some time and patience to do it right. The seals are easy to take out and put back, just take care there are no gaps at the corners and it seats all around.
