I started welding the floorpan in today and got the pan welded to the crossmember and rails. I worked from the middle out and got it fitting perfectly.. Tomorrow I'll continue on the rear part of the pan working from the middle out and then the pan to inner rocker. The firewall area will be last. Here's a few pics.. Just this area took all day because I wanted it fitting tight to the crossmember, all the other areas should go quicker. I am also on my second bottle of welding gas, so hopefully I can finish all the metal work on this tank.
