Hi Legend,
Maybe this can be helpful. It will cost dearly.... George at Marine Glass Specialties in FL.
Update-Called Taylor Made, and then called Grady to get the part number. The boat is too old so there was no way for Taylor to locate the exact parts I need, but the person I spoke with referred me to George at Marine Glass Specialties in Florida. They bought a lot of older Grady Parts from Taylor.
Phone numbers for who ever needs them down the road:
Taylor Made (518) 773-0636
Marine Glass Specialties (813) 926-3717
George knew exactly what I need. The price is extremely steep, but I still will go ahead and order the new glass, hinge, and vent pull from him.
