The bolts are the same spacing but the shafts are different. The GEN I are a metal screw-in type bushing for the arms while the GEN II's are real bushings. GEN II bushings come with the whole arm though from the dealer unless you order Poly Bushings from SuperPro out of Australia (or a authorized US dealer). Done that. Took 3 weeks.
