How do the outer rails tie into the car?
mustbereel:
What does everyone think that the TCP shock tower brace is worth in rigidity? It not only ties the shock tower to the cowl, but to the cross brace ("Monte Carlo bar"), too?
mustbereel: I now have just one question. Did you finish the backyard, yet?
the next thing you should try is solid welding all the panels instead of just relying on the spot welds or doubling the amount of spot welds. either way i think you'd be very surprised at the results.
where your front shock tower brace goes, you might want to use some steel welded to the side panels to layer the stresses better
you might think about taking the rear seat divider into a sheet metal shop and have some ribs rolled into it. even if it didn't add any to being rigid it would not act like a big bass drum.

Suprised because it doesn't change at all?
newer unibody cars have about three times the spot welds an old mustang has and they are much stiffer.
that was one of the old T/A tricks to stiffening up the unibody as well. it will make a big difference.
Apples to oranges. I contend that the newer unibody cars are stiffer, but NOT because of the number of welds.
I recognize T/A teams did it. I don't think it matters for a non track car that doesn't have to conform to an obscure rulebook.
I'll bet you a dollar ($1 US) it will not make a big difference. How much improvment (in %) do you consider a 'big difference'?
Here is some seam welding tech:

now, let's make what i'm talking about clear here. i'm talking about seam welding or doubling the spot welds in pretty much the entire car, not just a couple places. i'd consider a "big difference" between 5 and 10% maybe more.
Just for kicks I moved the 10ft bar back to the radiator support to compare with my orginal tests: 0.40". That's better than the best combo before (0.475") but I had neither the rear seat divider nor the jacking rails last time.
