Im not sure who you are saying have extra windshields but there is not that many. On this board skip20 has a couple (but he has a couple GT2s) I have 2, and there may be a few others with extra one but like me they have them because they have the cars.
I cant find the eBay listing to verify whether is for a GT2 or not. Some people have no clue and will tell you a Bradley GT windshield fits a GT2
I know this thread is REALLY old but I wanted to give you an update on Sunray for 2017. I have tried to contact them many times over the past few months. Calls do not go through, email does not work (not that it ever really did) and even 2 letters got returned as undeliverable. The facebook page they had disappeared months ago.
It seems as though they have disappeared.
I just got access to an oven and I may make new forms if anyone has a genuine interest. I have to finish my current project before I commit to it
Maybe if you post a few pictures and put a price that you are looking to get there may be some interest. Just keep in mind there are some pretty nice ones that also have titles that are ready to roll down the road (with a windshield) for $2500 to $3000 .
Everything is up to personal preference and how much money you want to spend. I am keeping my turbine wheels and keeping it 4 lug. I will ad a spacer to the wheels with extended lug nuts to push them out a bit more. When you spend money on something like rims you are not going to get that back when you sell the car.
