A-Body Frame Rail Connector

I just spend $50 on two lengths of 1/8" 2x3" mild steel tubing and weld them through the floor and into the subframes. No gaps and much better torsional rigidity than subframe connectors that don't weld to the floor.

I just bought the tubing to do my Valiant on Thursday, but I did this to my 1970 Dodge Challenger couple years ago.
