It was a matter of a strange and somewhat unexpected adjustment process. With the adjustment lever at right angles to the side of the car, on the normal setting the car was too low. Pushing the adjustment disc to the high position, naturally caused the car to rise, with the lever on the valve moving markedly towards the front of the car. Ha ha, to me this was a sign to lengthen the connecting rod to more or less keep the car at the increased height, but it actually had the reverse effect. It dropped the car. Hmmm.....
So I disconnected the rod that connects the adjustment lever to the anti sway bar bracket, and with engine running, I manually pulled the lever on top of the valve back to just PAST the centre position, thereby taking up the internal slack in the valve. Sure enough, the car rose to the height that is evident in the latest picture shown by Michel. Of course, the connecting rod now had to be shortened considerably to line up and enable fitment to the anti sway bar. Once the little bolt and the eye of the anti sway bar were connected, the car remained at the level evident now. At a calculated guess, the height of the front of the car has been increased by a little more than an inch. It looks about right now. Regards Styria
N.B. Moral of the story - sometimes you can't see the forest from the trees - or could that be the other way round. Whatever, it no longer matters.
