Jeez I wish I had a digi cam!

No my struts don't have studs as such, the top alloy plate (very similar to the one in the cad drawing) bolts to the strut tower of the body using three bolts, the strut itself then bolts to the alloy plate using 4 bolts to locate the bearing carrier to the plate.

Camber adjustment is made by loosening off the 4 bolts of the bearing carrier and sliding the strut either toward the engine for neg camber or away from engine for pos camber.

Where the very top plate of the system in the cad drawing has 3 evenly spaced curved slots around the perimeter, mine simply has the equivelent as sets of holes, each set consisting of 5 holes, castor adjustment is achieved by turning the whole top plate because once the strut is no longer in the middle of the camber adjustment slots it moves through an eccentric arc.

Sorry for the long post, sorry for the terrible explanation, maybe someone else can do better.

Cheers
