This would be the perfect candidate for a nice Outlaw. Custom pan or tube based chassis, fiberglass Speedster "tilt" front end, fiberglass speedster doors (glass the original window frames into the doors and run full side curtains attached to the frame with snaps or plexi "sliders"), fiberglass wide body fender flares, Fiat 600 (Abarth) louvered deck lid with rear stand-offs., plexi quarter and rear window (drilled for air pressure release, with straps against the rear window for support), and your nearly there. 914 gauges, Momo wheel, Speedster seats, aluminum elsewhere.
Hit the remaining shell with cement stain remover and coat inside and out with MasterSeries, spray the primer into the second coat of MasterSeries while it's still wet and you're good-to-go. Jammed up and jelly tight!
The rest is up to you, I'd do it up Cory-Style, hit the black ribbon some night, and go out hunting . . .
