Looking for pics of vinyl tops

[thunderroad]

I'm gonna have a vinyl top made for my 20' 1969 Formula and I want to give the guy an idea of what I want it to look like...but I can't find any pics. I want a top that snaps to the windshield, goes over a couple bows (that I have) and then snaps down along the deck just behind the back to back seating area. I've looked at a few classic boat sites but can't find any pics with vinyl tops. I tried to draw him a picture but he just kinda shook his head. I know if I took the boat to him he'd understand exactly what I'm talking about, but it's a couple hours away and I wanted to get squared away as to whether he could do what I wanted and how much before I dragged the boat up there.
Anyone got any pics or know any links for me to look at?
Thanks
