Ok,
Judging from your pic, it looks like I had identical issues in both places that you do.
The hood hinge location has two pieces behind it.........
Take some measurements of where the oval hole is..........
I cut out the piece making sure when I cut it out that the back pieces were not cut into..........
I then separated the pieces..........
Fit a good piece of steel into preexisting hole...........
Welded and ground down into place..........
Drilled 4 holes and oval hole..........
Re welded back piece back into place.........
The other piece I see on yours toward the firewall, I had to fix too.
I just cut out the bad stuff and welded a good piece in there too......
I hope this helps you.
If any of it did not make sense, or if you need any additional pics, just let me know
