hi guys.

My chevelle has had a hard life before i rescud it from the scrapyard. However i have something that bothers me alot, my Windows are in bad shape with scrathes and even a chip in drivers door glass. I know repop is not availeble, so does anybody know what other makes and years that interchangeable with a 75 2 door chevelle. I would love to find Nice door glass. 

I thought about getting some tinted scrath coated lexan and try to make new ones. I would use the old as a mold and heat the lexan with weight on it to get the curve it needs and then cut it to fit. But im not sure it will give me a result i can use. So i much prefer to try and find oem glass. But ill try the lexan if i cant. 

So all ideas and experience plus input is welcome.

Per Holland Interchange Manual:

'73-'77 Chevelle 2-dr; except El Camino
'73-'74 Century 2-dr; except Luxus & Regal
'75-'77 Century 2-dr; except Custom & Regal
'73-'74 Cutlass 2-dr; except Supreme
'75 Cutlass 2-dr; except Supreme & Salon
'76-'77 Cutlass S 2-dr
'73-'77 Lemans 2-dr

I've been down this road trying to find unscratched used glass for members on here. It's not possible. They all have at a minimum some light scratches where the glass contacted the weathered/gritty felt covered guide brackets when rolled up and down. Your only hope is to find some that are in better shape than what you've got. Good luck.

Thanks for the advise. It does give me more options as to finding replacement glass. However i know it is more than difficult to find glass without damage. I Think i will try an experiment with lexan to see how it is to work with. I can get some here with a smoke tint to it, in the correct thickness with a scrath protective coating. I have access to a large oven were i can heat it up. So if i can get it to curve right it just Might be possible to make up replacement Door glass. 

It Might not work but i need to get it out off my head, also it could be a weight saver as there is alot off weight in those doors. Im also contemplating removing the crash bars. I would not if it was a dd, but Being a weekend warrior, only driven on sunny days i feel it would be ok. 

Thank you for the list, i will have my parts guy keep a lookout when they Hunt parts in the us. I cant just buy and have it shipped here as the tax and shipping would kill my budget. So i have to place an order with my regular partshunter and hope they find what i need. Then it will go in a container wich is alot cheaper. 

Regards Henrik.

This process works excellent ! I just did my quarter windows which had quite a few deep scratches caused by me in the 80s.

https://www.youtube.com/watch?v=reb8rqsGvA8&list=FLwayUxLaZjuDGUrUtmg4lgw&index=56&t=0s

The video starts with using 320 grit. I had a couple of scratches that wouldnt come out. I bought some 180 grit. The deep scratches came out in less than a minute. Then I proceeded to 320 and on up to the higher grits like the video suggests. I polished with some Cerium Oxide paste. Came out very nice but still had just a hint of a haze on the rear side. The triangle quarter glass, rear side, is concave. So the 5" pads has a bit of a tough time sitting flat, but it can be done. I dont see any issues with larger glass. Anyway, I ordered some 2000 and 3000 grit Abralon pads but havent had a chance to hit the glass.

This process definitely works very well and is quick. All the sanding is done "dry". I kept my polisher at 1300 rpm as recommended in the video.

After I"m done polishing, I'll wash the glass with water then some 99 percent alcohol then I'll apply Groits Glass Sealant. That stuff is excellent, repels water like crazy and trash and bugs come right off. I clayed all the glass on my buick, alcoholed it, then hit it with the Groits sealant and its real nice.
