Arthur,
Give Ron a call. He is out of glass for the hardtop but has talked about having more windows made for years now. The guys who originally made the glass lost (tossed) the mold for some stupid reason. You might be able to work something out if you're willing to split some of the costs with him. It's worth a shot. He brings it up almost every time I see him, so I know he's been thinking about it
I'd jump on board but I have an original hardtop I'm going to be fitting instead. Good luck,
Jason
