69 Dart 340 Swinger Street/Road Race build

You are correct, USCarTool subframe connectors on mine. They are thicker than the factory super thin floor, but they welded in just fine. I carried the weld puddle on the thicker steel and washed the puddle up to the thinner floor. Turned out great. I debated on the tube through the subframe connector but i’m glad I did it. Took 2 hours alone, but turned out nice and kept the cable along the original path.
