I'm sorry to say even dealers won't be able to help. Body parts and electrical components are just not available anymore. This is the time to think out of the box. A plexiglass/polycarbonite company can mold a new windsheild, Vette bond and fiberglass can repair body parts, seat can be made. If you want it to look stock, I just don't see it happening, you want to customize it, make it better....let the build begin
I'll help anyway I can.
