72 quarter skins swinger

I doubt AMD was selling many skins once the full quarters were available. Typically you are going to have rust on the quarter to roof seam and at the trunk gutter. I bought the pair of skins for a 71 swinger I have that only need the lower rear portion. At one time AMD sold a patch just for that area but I have not seen those available for a while now.
Yes the cheap brands are much thinner and the metal seems very soft to me. Stay away from those galvanized patch panels that are out there. They do not fit and your better off making your own.
Just bite the bullet and get the full panel. If you find it in stock buy sooner than later because you dont know if and when AMD will restock. AMD seems to be out of stock of half their mopar parts at the moment.
