Thanks for the kind words, Mag!
Since I've actually been working on the car for a while, I decided to go back and find some pics of other repairs I've made. Here are some of the driver's floor and inner sill.
Old rusty and bent floor section:

Not the worst, but it needed fixing. I think it was easier just replacing the entire section versus just cutting out a part of it. Besides, I needed the inner sill section, too. Here's most of it cut out:

Pattern panel with surprisingly good fit:

The inner sill section now cut out and the panel trimmed, fitted and clamped into place:

Tacked mostly in. Had to go slow here to make sure everything stayed in line.


Welded. I did manage to cover the subframe mounting hole, but that was easy to fix.

Also made a patch for the front corner. Took a bit of finesse to get it right.

But in the end, it turned out great.

Now moving on down the sill...

Cut out the rusty bit

This is part of a pattern inner sill, but I didn't like the part I needed (the middle), so I cut off one of the ends and flipped it over.


The whole side is now solid metal again with all traces of rust removed.This was a big moment for me.
