Jeep 4.0 in 69 Barracuda

Ok everyone. We are on a holding pattern for a while, and I have been doing some research on the next item out side of my skill set.

I have a stripped hood nut plate. 1 of the 4 is not usable. This maybe a situation where its better to replace than repair. There are those who believe there is not enough metal to drill and tap for 7/16. And of course those who do. I have not seen any instructions for cutting the plate out and replacing it with new. WildCats can get me a replacement for $400 if I pick up.

Is this the time to move to fiber glass? Is there a good fiberglass company people recommend?
