Not sure how original you want to keep the car.
I did a version of this to my shock towers. For a couple extra hours and a little bit of material its a good way to reinforce your shock towers. Basically two scab plates, one welded to the outer firewall the other welded into the shock tower, run a brace from one plate to the other, really ties the front end together. You can also run a rad support brace from one fram rail to the other.
I used square tube to mimic the factory support. Ran it right underneith it on the same angle, you can hardly notice it.
This pic is not of mine I used it just as reference.
