Front trunk reinforcement?, Where would you put tubing? Options

[plymouth37]

I am thinking about adding reinforcing tubing to my front trunk/shock tower area and would like to see what you have done to your cars.
Where do the tubes need to be located?
I would like to keep the stock gas tank but if I have to notch it here or there it isn't the end of the world.
Also the radiator shouldn't really be a huge concern, I can mount it anywhere.

I am thinking something like this but in the front, not full tube chassis but more tube, less sheet metal.


Here is how it looks now.


Thanks for the help!

As you know, a full rollcage with ties to all suspension points would provide the most stiffness/protection. But since my car will be a fun street / occasional track toy, am not considering a full 'cage. In short, I don't plan to add too much tubing in the front trunk of my Suby-engined project; I merely plan to tie in the front A-arm mounts transversely. Kinda like the 914GT projects. That will also provide a strong lower mount for the radiator in my project. I'll also seam weld the front towers like I did in ass half of the car.

The factory front wall probably provides some degree of stiffening between the strut towers, but I've never heard that it is particularly weak. Whatever you do, I'll be sure to watch -- you've got a killer project!
