Mike,

Can you show a pic of the top mount dis-assembled, i.e with the caster/camber plate removed from the base plate?

And to clarify, the ford ones Mark showed earlier are not actually adjustable, they merely widen the top mounting dimensions contain numerous M8 high tensile bolts locating the top mount to the modifed tall turret..after being involved in several Grp'a' and wrc cars they have never been an issue on both tar and gravel cars...
