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 1/4" was taken up by your motor plate, but if he did it, that would throw his pulley/belt alignment off, no?
