Made my own. Got sheets of 1/8" lexan and used the old glass as a pattern. Taped up the border and spray painted it with Krylon. Take your time and cut it slow with a very fine toothed jig saw or band saw if available. Rough out the blank and support it on a flat table (like 1/2" plywood on saw horses) to finish cutting it. Key point here, TAKE YOUR TIME.
