clutch fan gap too short

MILL a 1/4'' off the water pump housing , I did to allow for my motor plate -----
also chucked the clutch up and took .060 off of the fins , you`d be surprised at how uneven they are to start with .

That's a great idea - but I don't currently have access to a mill. Where I live there aren't really any small job machinists like there used to be.
