The inner rocker fits ok. Not awesome, but it works.
It is a little long at the rear, and the angle is a little funky where it meets up with the front flange. Not a big deal.
Some progression shots of what feels like a million tack welds. 3 in a row was about the max I did. No need to heat things up a lot.
Note the high tech go/no-go gauge at the rear of the door opening. That was dimension of the gap when I started disassembly. I'll take a hokey tool over guessing.

Maybe I'll get more done this coming weekend. It was a good stopping point for me. I need to re-shape the rear edge of the inner rocker, patch the front floor, and get the braces in next.
