1971 Slant-six ballast resistor ID
An advantage of the original mounting location will be the additional protection against rain or snow when the hood is opened.
For the terminals, if you want to restore to original.
The closest commerically available is a Series 58 made by Packard Electric, sometimes listed under Delphi or Aptiv.
Female terminal 2965471 is brass and 1201601 is tin plated brass specifically designed for two 14 or 16 gage wires.
A terminal for one 14 ga wire will also work. Just make sure the wires are side by side so the conductors for each get crimped properly.
This is the original from a 1967.

The original plastic insulators should work with the 58 style.
However be aware that plastic insulators made for Packard 56 series female terminals may or may not fit.
That happened to me.
Exterior differences are subtle

The 56 series is more common and you may find that is more practical to just use 56 terminals and housing.
Seen that on some reproduction harnesses. It would take a real expert to know the difference.
The above crimp isn't great - the conductors should extend out from the crimp.
The one below was even worse
I don't have any suggestions for the firewall repair. From the photo - this car is beautiful and deserves a nice looking repair.
