FYI the Mopar tubular front sway bars are ready to go. Part numbers are as follows

55903 64-69 B-Body Mopar 1-3/8" FSB
55904 70-72 B-Body;70-74 E-Body Mopar 1-1/4" FSB
55906 67-72 A-Body Mopar 1-1/8" FSB

73-76 A-Body Bars will be coming soon as well as 63-66

Dave, is the benefit of using the tubular bars less weight than the conventional ones? I just bought and installed the rear sway bar on my 1971 Dodge Dart GT and am very pleased with it.
