Bit more garage time today, picked up some lower arms ahead of fitting the front struts so I could get the sway bar and everything fitted up and ran into a snag.
The arms went in a treat but there is NO way the wide sway bar mount and bushes will go on, first the bushes are for a smaller diameter sway bar (mines 22mm) and second it seems like the bracket is WAY to close to the edge of the bar. Not sure if that's normal but the sway bar will definitely bind on the bracket when cornering, there just isn't enough clearance on the inner radius.

My solution is to dump the wide bracket, I need to order new bushes anyway because the ones in the kit are useless. So I've ordered standard width 22mm white line bushes and I'll clean up and paint the standard sway bar bush brackets and run the standard width bush on the wide bracket body mount. This means I'll still get the castor from the mount without the headaches of those brackets and bushes.
Also brains trust, should there be a metal bush for the end of the sway bar that goes between the washers and through the rubber bush on the control arm? Can't remember if there should be one there and the workshop manual doesn't specify. Pic for reference.
