Quarter panels, let's cut em off and put new ones on.

With full quarters you'll do more metal related labor, but way less body work after it's done. Skins can be tricky (6ft long butt welds, filling, blocking, ect). With skins you also have to know where to piece them in to hide it the best. I've never hung a quarter that lined up perfectly out of the box. The tolerances stack up throughout the car and no two will fit the same. It's one of those things where you just gotta jump in to see what you've got...and then do what you gotta do to make it work. A nice selection of clamps and vice grips are pretty much mandatory.
