Subframe connectors/torque boxes question

70 Dart 340 - torque boxes on 4 speed cars from the factory, same with 68-9 and , and I believe all the big block Darts

I have USCT torque boxes and subframe connectors - they made a great deal of difference in stiffness on a hard launch and going around corners. You don't realize how much flex your car has, until you eliminate it...
