Valiant 69 front inner fenders

Hi,

I'm doing body work on my Valiant and for some reason, previous owner cut inner fenders of and replaced them with a tube.

Here is a picture:

when I got the car I made inner fenders from fiberglass but I'm wondering if I should replace them with correct inner fenders (more stiffness ??).

AMD has some for sale:

The question is are they enough or is there something else I need?

The main problem is that the cap between the front fender and door is to big.

Not the best picture but you get the idea.

Here is a picture I found on the web and I can't tell if there is something more I need or not:
