I got a cutlass that i removed the vinyl top from. its from west coast canada, but had no rust suprises. Body work needed is to grind out the trim studs. The roof/c pillar joint will look very ugly, so that will have to be sanded out and then filled with good body filler. And since the original vinyl trim is attached to the fabric at the rear window, you will need to attach studs to the rear window frame for the hard top trim.
