[Healeys] A arm connection at fulcrum

[Stephen Hutchings]

I've got a question about the tolerance where the A arm/ kingpin meet 
:  the manual says there should be a tolerance of 0.002" once the 
threaded bushes have benn turned back one flat.
Fine, only the cork rings don't sit all the way into their recess, 
and I think that the compressed cork rings would make a feeler guage 
measurement impossible.
So, are my cork rings too thick, and should I trim them before 
fitting the a A arms (lower wishbones).?
Thanks
