If I'm understanding (and buying) correctly, the bushings are different in the newer (2010+) FJ's than in the 4th Gens. I believe that the bolt diameter is larger, so you'd have to drill out your 4R to make them fit. The coils will fit regardless. I'm in the process of acquiring a set of 07 bils from an FJ, and just picked up a set of coils (and stock shocks) from another FJ. I very well may be wrong and am more than willing to be corrected if others have better info, but that's just my understanding.
