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, or if you've got an intact one you could send it to him. HOWEVER, Rick is very conscientious and would really prefer to have the rv there to make sure the finished product is perfect. If you are willing to reassure him you're happy to do any trimming yourself, he'll likely be willing to ship a finished product to you. (Rick uses a dremel mounted to a work bench to do his trimming)
