I removed the vinyl top from the 79 cutlass I had, pain in the *ss to do on that car. I did it because it was shot, and I felt rust bubbles under it. Peeling it off, was the biggest problem, it came off in little strips about 2 inches wide, the glue.....I still don't know the best way, I got sick of scubbing with adhesive remover, and resorted to paint stripper :lol: . The top also was put on before the windows were put in, so in order to get all of it, the quarter windows and rear window need to come out. Quarter window will not require anything different to reinstall, just put moldings back on and glue em in (urethane).. The rear window molding is another story, it's just a one piece black plastic molding riveted on the car, completely different from a non-vinyl top car. so you will need the molding from a donor car, also you will have to figure out where and how to put the studs on for the retaining clips, or get screw on clips. After that, you now have all the molding studs to take care of, knock em off with a grinder or just put the moldings back on the car your choice. Remember, that top covers up Unfinished, and half assed bodywork, on mine they used almost like a seam sealer rather than lead, or filler. Be prepared to possibly have to weld in patches for the gap left in the roof and quarter panel seam, some are worse than others. For the record my 85 cutlass was nowhere near this much of a nightmare, it was nicely finshed under the top. So if your top is good, and the roof is good under it, I wouldn't mess with it unless you really hate how it looks. Be ready for all that and probably more, I may have forgotten a few things as it has been almost ten years since I had to do it, lol.
