What kind of Windshield Snaps?
 

Guys

I have a 35 Lightning with a full camper canvas and plastic windshield and sides. These have snaps on them that line up with the top windshield rail on the boat. My windshields rail doesn't have any snaps on it for the plastic windshield to snap to. Does anyone know what kind of snaps the boat windshield uses. I tried the 7/8 and the 3/4 standard windshield snaps you can get in the store and they don't work.

Thanks
