Yup. Not the oldest one I've seen brought back from the dead, but it's moot. The original poster hasn't been seen for well over a year. From his profile-
So if I am running a mini tub kit and spring relocation (US Cartool) on my 1973 Duster it's obvious your A-Body Rear Sway Bar won't work.
Can I just use your narrower E-Body Rear #6908 Hellwig rear sway bar with longer pins thru the frame?
72BBSwinger runs the #6908 Hellwig bar on his Dart with a 3" relocation and mini-tub. The A-body frame rails do require longer hardware than the E-body rails if you actually go through the rail, but with the relocation that isn't an issue.
