NA to NB frame differences?

I'm looking to fix a NA that has a medium hit to it front end.

The damage is in front of the shock towers, a wrinkle in the frame rails about a half inch. It's pushed the nose, headlights and hood latch back about 2 inches and down, from nose dive under braking then contact.

So, I am looking to cut the NA at the rails in front of the shock tower and put on another front sub-metal, centered around the core support due to a fairly well centered hit to the center of the nose.

Is the NB sub-metal in front of the shock towers the same as NA ?

This will give me many more donors to pull from.

No. Discounting the radiator support that is very different because of the different headlight styles, the rest of the underlying sheetmetal is different enough to be a huge PITA to make it work.

No, not worth the headache.
I have done quite a few hit like that and it not as easy as it looks.
I may have some 91 frame rails.
