The IRS crossmember is in the top picture. He used the original crossmber, except he trimmed of the ends and welded in-between frame rails, then added a few gussets. A truck in florida was actually the first to do that full tube front to back. It was not clean, xtreme built it. The only thing I never liked about everybody that did that rearend swap, is none took the time to step/curve the upper frame bar inwards so the tires are not baiscally resting on the tubing.
