What # is your car. Radical Roadsters here in Houston has started stocking, cut, polished Lexan MR-10 replacement windshields for Backdraft cars. I put one in my first Backdraft in late 06 and have taken rocks, birds and barely even a scratch. I just purchased BDR #621 and told James at Radical Roadsters to order one for me. My windshield will crack eventually and when it does, I'm putting another Lexan one in. He recently ordered 4 and has at least one spare for sale. Contact James Yale at

Tell him Bill sent you so I can get my usual finders fee (1 Shiner Bock). Good luck.
