Not sure if the question goes here. I am looking to replace the side glass front and rear on my A Body. Any good place to get the items from?
When I was doing some research on glass replacement for my 1972 GS Stage 1 restoration (a couple years ago), these two companies seem to come highly recommended. I was after replication of proper dates codes etc. - not sure if you are concerned about that, or not. https://ecs-automotive-concepts.myshopify.com/collections/gm-glass https://www.autocityclassic.com/1961-1970-buick-glass-page-1/
I used Auto Metal Direct glass on my 67. Very happy with quality and fit. I bought it from Jegs. No date codes, but I am not concerned about that. Not sure if you are.
Same question with my windscreen. In some direct sunlight situations it's peppered with small pinpoint flares.
I've bought several full front and side glass sets from Auto City Classic. They ship FAST and the quality is decent. Plus you can get correct date coded glass if you want.
