I don't know how far you would want to drive to pick some up, but I've got the following glass from a '79 Burb.
The windshield, Side Door Glass (should fit a blazer). The rear side windows are also good, but I think they're too long to fit a Blazer. I already removed the windshield. Hadn't removed the rest yet, but if you're interested I could. It's all in good shape, i.e., didn't notice any big scratches in any of it. If you're interested I would let you have all three pieces (windshield and both doors) for $100. I'm located just south of Grand Rapids, MI.
Let me know if you're interested. Thanks!
