Overall, I really like this one-piece floor, I just needed a small amount of tweaking at the firewall flange. For some reason, the last couple of inches of the flange angled down which didn't match my firewall flange which is completely straight across. Instead of forcing it into place(it wouldnt of fit as nice), I made a pie cut and will put a little patch in. No biggie. Here are before and after pics and the area at the firewall it should match up to, then installed and tacked.

here are the areas to be welded cleaned and sprayed with weld thru.
I also put the cab on the floor to insure it was on a solid, flex-free surface.
