The firewall was in pretty good shape but I wanted to close some of the penetrations. I'll just redrill anything that I need later. The previous owner had also tried to rework and deepen the firewall recess but this area didn't look too good to me so I planned to replace it.
I used painters tape to make patterns for the larger irregular shaped holes and just measured the round holes and fabbed a few patch panels and welded them in via tack then butt weld perimeter.
I then cutout the old recessed area started making a replacement panel. I had purchased a leather shotbag and a set of nylon hammers so I used that to rough shape the new recess panel. Once I had the basic shape then I used the english wheel to roll out and smooth the panel into the contour I needed. I then trimmed, fit and welded the panel into the firewall.
