I lost a little over 50% of the weight on mine. I would say that you would stand to shave a good 11-12 pounds with the Lexan. Look if Percy's speed glass has molded ones in stock of if they can do it for you on a call in basis. Those A-bodies are very popular. It's well worth it in the end. You would also have to apply a good sealant all along the windshield brim to make sure it all seals against leaks.
