David,
I think I'd buy the lexan ones you are making for $250 and forgo the glass sidewindows. My opinion only. I am interested in buying one set of the Lexan if you go into production. Have you had a chance to measure the distance between the two mounting hole on the door sill yet? Let me know as I want to make sure they would fit my JPS. I assume they are the same as a VS but want to make sure.
Thanks, Bruce
