Welded rocker rail brackets to rocker sills today. Bolted up rails and tack welded in c/m tubes in the rear. Holds the body from flexing around. Have to get another tank of gas before I can finish them up. Meanwhile, I made a copper ground contact out of an old length of battery cable. I think it is working much better, now. Mig welded axle housing to tubes. Was a walk in the park. Single pass. 150 amps.
