quarter floor pan replacement

Has anybody bought the replacement floor panels from Quadratech? I just got a front drivers side section, and I'm about to start cutting out the rust. Just eyeballing it, it looks a little long. Should these fit right in, without messing with the cross bar that the front seat bolts to?

i thought that they where kind of a trim to fit type of panel

Sounds right. In my case, the rust is mostly stopped just ahead of the seat cross brace, so I guess I'll just cut the new panel to fit from there to the front.

Check out RockAuto, I seem to recall their floorpan replacement prices being way better. Not sure on quality comparison though.
