Hey Jim,

I'm not sure all Vertex fans are this way, but the one I was fitting this weekend has a small radius at the base of the stub for the outer pulley. That radius didn't let the first shim sit flat. Had to machine the ID of the first shim a little larger to clear the radius, now the outer pulley bolts solid to fan. The stock fan has a relief machined in that area just for that purpose.

If you set a couple of shims on, then lightly install the pulley, you can see the light through the shims.
