One question though, why did you try to cut old quarters exactly to fit the new ones? I'm planning on leaving about 1/4" and just bending the old metal back (like is recommended on the rustrepair site). The only places I'm cutting to fit is the very back near the taillight, and where the trim goes.
Oh, and for a spotweld cutter, I've got one of these, the 11093, and it works great. Takes a bit of practice to get good with, but once you've got the hang of it popping off body panels is a breeze.
