I have a couple left over windows from my build located in Grand Rapids MI. I had a really nice Classifieds thread written, but for some reason it didn't post.

Since the original thread didn't post, I included a photo in eBay of the windows during installation on my bus. The 2-3/16" depth is perfect for my Blue Bird frame plus 1/4" interior ply.
I've gone 9,000 miles on these windows with good results. Let me know if anyone wants'em. Cheers,
