So, this hole....
Turned into this....
While cleaning up the area with the wire wheel, more and more pin holes started showing up. I had planned on cutting all of that area out anyway, but in a different order.
I had started a patch at the top. Because of the compound curves (the area is kind of bell shapped), I had to get creative with the metal.
The patch I started with. Idea was to form the top piece, and then build a patch for the vertical section, welding the two patches together (not to the rusty, holy metal). Can also see the outline for a future cut.
I just couldn't get the top piece how I wanted without attatching it at the bottom. So out came the cut off wheel and that entire section came out. Along with part of the A-pillar that had some pinholes. Found tons of bondo in that area too, either from an accident repair or an attempt to hide some holes.
After a few hours of cardboard and 16gauge this is what I have.
I did remember to make a template of where the hole for the fresh air vent was. Once it's all patched up I should be able to smooth out the curved part some with a little hammer work. I won't get carried away as it'll be burried under the cowl and no one will see it. The top piece is 22gauge, so it's easy to manipulate.
