A little more...
This weekend a few buddies came over to help out on the the car, well, it was supposed to be one but four showed and more talking than work was done, but they got to check out the car for the first time. What basically got done was we positioned the body in it's finally spot and we lowered the passenger side 3/4" to level the body out. Friday I went and bought 5 sticks of angle iron to get it all done.
Last night I cut and tack welded in the floor support using angle iron. For just being tack welded at the moment the concept seems very sturdy.
Next I'm going to weld in the body mount rails that bolt up to the heater channels.
