Can any experienced corvette glass guys tell me if windshields and rear glass change shape over time? Some old glass I have doesn't seat flush in the frame and a bit difficult to determine if its the glass or frame. Also any recommendations a good suction cups for install ?
I can tell you that old glass will "flow" over the years. If you have ever been in a 50+ year old house you will see it has ripples where it flowed downward. I assume auto glass would do the same and would loose it's shape if not stored properly. However, it may also be your birdcage.
Harbor Freight sells some 4" suction cup devices that work well on glass and are inexpensive. Check out their web site.
The glass in my 66 is original to the car it had been out for years then back in for years then out again. It did not change at all. It is back in and fits well. And no I didn't need suction cups.

We have a hundred year old farmhouse, and if glass is going to “flow” anywhere it’s Texas in the summer. While there are all sorts of inclusions and distortions in the glass, they are all a function of how the glass used to be made IME. Can’t imagine something as stable as glass flowing? Certainly hasn’t in my very small sample of one house. But you learn new stuff all the time. I would wager this is a birdcage issue and not a glass issue.
If left undisturbed at room temperature, glass really doesn’t change — no matter how old it is — says Michael Cima, Professor of Materials Science and Engineering and Faculty Director of the MIT Glass Lab. Contrary to the urban legend that glass is a slow-moving liquid, it’s actually a highly resilient elastic solid, which means that it is completely stable. So those ripples, warps, and bull’s eye indentations you see in really old pieces of glass “were created when the glass was created,” Cima says. They are the result of old-fashioned glass fabrication methods, not aging.
The only way I think a windshield could change is by warping due to being unsupported for a long time and the safety gel between the glass faces allowing movement of some sort. I've no clue as to if this is a real possibility, but the glass itself won't change.
