You'll get more strenght from the double x's i mentioned before tho...i would think you'd want some overkill. I think the double x's would help take some of the weight off the firewall which you are also technically not truly welding up to. so its just an attempt to balance the stress points and distribute.

You could doubleX into an enclosed rectangle and the rear of those rectangle go flush against the firewall as well with backing plates+riveted....and call it a day. That would be the most strength....and skip the top bar...altho that would help keep center.

i think by the time you welded in all the reinforcement plates to mount the tubes and the brace tubing you would end up being at the same weight if not more

You will also eat up room in there with all the extra tubing running all over the place

That looks good! Keep in mind, the only thing you want to flex is the shocks and springs, not the frame. Unless the frame is completely rigid, you'll be chasing your tail, trying to find the "handling issue"....

Weight is not an issue at all and it's not gonna eat up room. Think of all the room you gain by having no shock towers. It's a great trade off in my opinion.

yeah nothing personal but you are like building a semi tube chassis car and cutting out the unibody frame
here and there so it's not really solid nor light

the right thing to do would be to skin the car's body and build her from the ground up like a Nascar.

I not too concerned about weight. This isn't a race car, it's just a cruiser. I might take it out to the local car cruise Sat night.

The thing is I'm just a shadetree mechanic. I don't have a shop or even a garage. I'm doing all the work in my front yard, so a full tube frame just isn't possible.

Getting back to beefing up the frame rails, I do have that stripped out white donor car. I could probably rig up a way to flex the rails and see how strong they are. Then add bracing to see how effective it is at reducing that flex.
