FYI, I recently found a plastics shop which can fabricate replacement, wrap-around cab-over windows for the Sunraders at $175 each.

The owner's name is Rick.
My passenger side window ('85, narrow profile) was cracked badly but intact. I dropped it off at this place and within a few hours Rick had the new window done. I took the rv back and he helped me install it. It had to be trimmed a little bit, but once in fits perfectly and looks fantastic.
Rick's got my old window and could use that as a template
