Bracing shock towers?

To give you an idea about flex in unibody I have a early -a with a 360 4-speed. Drove it for 2 years and noticed the quarters geting wavey, doors hard to shut and the paint cracking at stess points. So, I bought a Mopar Chassis book pn p5249441 It helped. I had it straightend at a frame shop and added subframe connectors using 2 x 4 square tubing and boxed the front sub. I also got inspired by a buddies mustang and fabed up the compartment braces using steel conduit since going across the towers are geometricly imposible.

In the chassis book it states 3 things to stiffen the chassis.
1 subframe connectors
2 box the sill and front longitudinal
3 box the sill and rear longitudinal

But they are assuming you are leaving the original design alone.

I was going to upload picks of the bracing and cracks but can't resize the pictures to fit.:angry7:

The stiffer the chassis is the better the suspension will perform and put more power to the ground.
