No excuses for the bushings. That's not acceptable. But the springs themselves......
I've been having the same dilemma with the fabled OME springs. You and I have both spit out driveshafts as well. All signs point toward NEEDING a traction bar.
At this point, I've got 2 complete sets of OME springs, a set of OME helpers, and my old set of bastardized rustys springs. I'm going to do what I can sometime over tr summer to make some ultimate leaf pack.
