Floor Pan Questions

I've heard nothing but good things about the Harbor freight spotweld cutter, and heard you get a lot of mileage out of them before they go. I have a fleet center near my house and all they had was the $12 one, I think it's a Malco or something like that.

The "roll up pan" to me is the piece under the rear seat that starts at the rear of the floorpan and defines the rise in the rear footwell. It also has the rear seat mounting bracket attached to it. Although my car is pretty solid, and am trying to save every piece in case I need it, but if I don't I would certainly sell that area to you. I have also found on cars where that area is rusted is that the pan that also welds at the next rib back and goes over the rear axle is also rusted around that same radius. The way those 2 join at the rear of the floorpan creates a nice little void in there that can hold a lot of moisture!! I am also trying to save this area just in case, although it is cut at the arch of the frame, where there would be enough metal do do a nice repair on that area. I'll keep this updated as progress continues. Geof
