After a search of the net i have found a drawing of the spacer that westfield araldite the the standard bearing
I think i'll get one made up at work but not really sure what the best material to use would be?
It says on the drawing that it has to me 19mm depth but, different people say different things ranging from 19mm, 19.5mm or 20mm
Thought other people might find this useful (maybe the andy's at saturn could undercut westfield on this and make it more available to the public
)
