I am wondering why I wouldn't want to fabricate my own Aluminum hard top on my boat. I would like to attach it to my arch as well as two points in front near the windshield. Then in the back attach the aluminum to the back side of the arch and 2 point near the back of the boat. I would consult with the upholstery shop for mounting zippers for the isinglass windows Please let me know if I am stepping into a pile by doing this. Thanks Rick We specialize in fabricating one of a kind driveway gates. But not boat tops!!
