When I bought my 240 2.5 yrs ago, the tire place I took it to said it needed 1 LBJ and all LCA bushings. The quote for the LCA bushings at that time was $450. That did not include redoing the control rods. This an established company with a good rep, not a Tire World discounter where the mechanics are continually rotating. And that was on a Fla car -- no rust. The price quoted to you seems rational.
