All I know about them is that when I was looking for a replacement safety-glass windshield & frame for a 23' Mako (did I say that?) that I was thinking of buying, they were extremely helpful. A friend of mine who runs a boat restoration shop up here in Massachusetts recommended I call them, so I did. The boat was a lemon so I never wound up buying the windshield frame & glass.
The have a website too....i think it might even be..
