Also, I cannot overstress the amount of difference it makes changing the two sway bar mounts at the very front of the vehicle. Remember the sway bar and all associated mountings control the fore/aft motion of the front wheels completely. Basically, there's no quick fix - just replace everything rubber-y at the front end, including strut top mounts (shocks good idea to replace too while you're at it) Although disc run-out is specified at only a few thou max, I've found this makes little difference to shimmy with a stock setup. (as long as its not ridiculously far out) Hope you sort it. ('79 UK 320/6 auto)
