Cj CJ-5 Frame boxing ??

I am partially boxing in my frame on my '74 Cj-5.
Since the front is boxed from the factory, I am concentrating on the rear sections.

You can see the new metal on the left and the right, but I'm wondering if I should box in the middle section (between the crossmembers).

When I boxed the frame on my 75 and my brothers 49 I did the whole thing.

What did you decide to to? How did it turn out? I have my body off right now and I am looking to box in only the areas you have shown in your photo. To me it seems to add strength to the critical areas, while allowing functionality and ability to wash mud & crud out from within the boxed portion, allowing some longevity.

I have always wondered how much more flex advantage the early frames had over the later CJ's. I never considered the early frames having a problem with flexing over obstacles. Why change that?
