"He took measurements and said the glass was about 1/4" too tall for the window opening."
Is the window itself/alone taller than the opening? No
If yes, you are in a bind (excuse the pun).
The seal + window is a very tight fit.
Presumably, the installer was using/pulling the "string-in-the rubber grove" trick/technique?
yes
The window fits in the opening, Tim. But not much room around it. The "glass guy" said that the glass needed to have 1/4" space all around when placed into the opening. He ordered a glass from a manufacturer in Canada and is going to compare it to the glass I purchased from Classic Chevy (made in Taiwan).
The Original windshield was fine other than a crack down the middle from top to bottom and a couple of BB strikes. I never thought to keep the old glass when I removed it. I measured the cross section of the Steele Rubber window gasket and it measures .325" from the top of the base to the bottom of the window groove. At a 1/4 space all around it would compress the gasket .075". Does that sound right?
