Frame upgrades 68 Dart

Take a look at this picture of the underside of my car and you can see where the torque boxes are welded into the frame just in front of the rear fender opening and just behind the front fender opening. The subframe connectors are then welded into the two obvious open ends of the long frame of the car in front of and behind those boxes. I bought the frame stiffening kit from US Cartool. Their parts were excellent and basically fit right into the frame without much massaging.
