Glad to hear somebody has had success with used corner glass...but every pair of corner windows I've found at swap meets or on Ebay has at least one piece scratched badly. Polishing can help some, but will cause distortion if you have a deep scratch. So... as part of a major re-furb on my truck, I popped for a brand new set from The Glass House in San Dimas, CA . They are beautiful quality, but pricey at about $275 a pair. They are made in several tints so I was able to match the rest of the cab glass. Very nice folks to deal with, and I like the idea of supporting a vendor willing to make the investment in a product that's never going to be a huge seller. They make a number of other interior products and will send a free catalog on request.
