My first Mopar/Questions?

I would agree with both options depending on how extensive the rust turns out to be. If it is just a couple small spots like we have just last week dealt with on our 71 valiant which as you know is the plymouth version of the scamp. We replaced what was bad, to me a better option than peeling off the roof skin, especially for a guy with no tools or skill in that area. The roof on my 1/4 vinyl javelin is completely rotted away, so we picked up a parts shell to peel the skin from one to replace the other. As no one makes roof skins for amc cars. So get the car home, remove the vinyl and evaluate from there. Our valiant was only rotted where the seams met.
