New windows for my Y-37
I just replaced the windows on my Y-37, but took a different tack. Because the old windows had cracks wherever holes were drilled, I didn't drill any. I used lexan material, and used silicone caulk. My windows are inset, so I filled in the gap between the window edge and the cavity edge. It looks better than the original, and has more material between the elements and the cabin.
