Torque Boxes vs. Frame Connectors

I also say frame connectors, an agree with costs of these aftermarket engineered wonders, .... I get 2 x 3 inch tubing, costs very little, get whatever thickness you want. It has been argued on here many times about where to cut the floor and weld to floor. My take is that is way overkill unless a race car ( which I know would have a cage!) or track car. If you sell the car larger to a purist he could simply cut and grind where the connectors were.
MAW mopar didn`t invision 6-900 h.p. streetcars running around back then. I used 120 wall, 2" sq. tubing, w/ the driveshaft loop welded to them, and the 6 point cage. I didn`t want a roll bar, but from past experience knew the 505 would twist the body if it ever hooks up. I always ran w/ the back seat down in my new one back in the day, liked the way it looked !. Like a business coupe.
