Definitely check those ones! The rose bushes (mounts) can develop a lot of slop in them very quick. I had mine cut off by Bilstein Motorsport and small diameter rubber bushes put back on, which I then swapped for poly bushes. Problem fixed but expensive. Grit chops those mounts out quickly.
Re the watts linkage, I'd be using the stiffest bushes available. I thought the factory ones were spherical bearings also with a nylon bush around it.
