Default Compatible Windshield Replacement

Hello all,
I've perused the forums a bit but can't seem to find any information specific to what I'm looking for.

I just recently picked up a 1975 Chevrolet Van30 (RV conversion by Mobile Traveler) and am in need of a windshield due to a single crack in the middle. It's not looking like the glass is easy to find and Safelite is outright ignoring my inquiries. So my question is: do any other years fit this vans windshield dimensions? For example does a Windshield listed to fit a 67-70 model year have any significant difference in the bends or shape? Looking at pictures I am not seeing any change. But it's alot of money for a maybe.

Two entirely different vans. The early model has an almost flat windshield. The later model is much bigger with a slight wrap around glass. You may have to do a junkyard search.

If your camper is a cutaway van with a stock GM windshield frame, any 1971-1991 windshield should fit. At some point around 1991 they went from a gasket install to a urethane install and I am not sure if they just made the glass a little larger or what, but I would not be shocked if you could use the late glass and urethane it in as well.

That would be awesome, so far haven't found anything available near me. I'll start looking into those years now too.

Thanks!

It is not looking like the glass is easy to find and Safelite is outright ignoring my inquiries. While searching for parts I also came across some honda talon accessories sites that surprisingly had some useful cross reference tools for locating hard to find glass and parts. So my question is do any other years fit this vans windshield dimensions? For example does a Windshield listed to fit a 67-70 model year have any significant difference in the bends or shape?

The G Series vans were pretty consistent across those years so the 67-70 glass has a good chance of fitting. Cross reference the NAGS number to confirm exact dimensions before spending the money. Also try salvage yards, Copart or Facebook Marketplace as NOS or used original glass for these vans pops up more often than you would think!

Why would someone bump a 4 year old thread with incorrect information?

71-95 are the same shell, 66-70 are entirely different. The shell carries over to 96 G30 only, G10 and G20 were replaced with the Express.

The only change in 71-95 is they go from a gasket to urethaned in place and I believe to accomplish this they made the windshield slightly larger so it would sit on the pinch welds. One would have to compare the glass side by side or find some chart with the dimensions (maybe an interchange book) to determine for sure. It's just as possible there's no change at all.

You are correct. I own a glass company and the later glass is a little bit larger and won’t fit in the gasket unless you grind on the glass in the upper corners.
