I had a a couple more hours to spend on it tonight. Slight change of plans. I installed the rear outer floor piece. The main reason was so the rear pillar had more support. I plug welded from the underside - holy moly, it makes me want a cheap Harbor Freight spot welder...
I spot checked the rocker again, I think it will turn out "ok." Next I need to do the kick panel, etc. I forgot all that stuff ties together at the lower A-pillar.
Then, ON TO THE ROCKER PANEL!
