1965 Barracuda

Welcome, I know windshields are available and that a reputable glass shop can order them. There was a post by Slantsixdan with the part number you can probably find it playing around with the site's search feature. One brand is manufactured in China and you don't want that one. By the way, all a-bodies '63-66 share the same windshield. As a '65 Barracuda owner myself I learned early on to look for '65 Valiant parts because that's how many of them are listed.

Also you'll want to study up on how to install it with the proper type of sealant.
