For starters you might want to get a hold of Rex marine in So. Cal,
http://www.rexmar.com/ You can ask them about the windshilds also, There are a few guys around here that can make you a Windshield,, [CA, & there is someone in lake havasu to.]
Because of the style boat you have you might want to check out Performance Boats forums.com Those guys in the jet and V Drive area of the forum are pretty good with helping out with your style boat. And if you do go check it out over there, Look for someone called "Rexone" he is the owner of Rex marine and he will help you out also. Good luck.
Heres one place for you on the windshilds.
