  OK , if I understand correctly the 4 slot flange bolts to the pump
and the fan bolts to a surface that is hidden by the fan  . Got a mill
and a boring head ? Is the current fan's base circle diameter big enough
to drill the bolt pattern of the new clutch ? I could adapt that fan to
that clutch in my shop .

Two notches in the fan hole might get it over the flange without losing
centering. Does the clutch body size allow you to tilt the fan and slip an
edge of the hole into one of the slots to gain clearance?
 

I think the answer is "yes", but the clutch centering boss is 2 5/8", while
the fan bore is 2 3/8". There's enough metal on the clutch to turn down the
centering boss to 2 3/8", if that runs true enough a new bolt circle on the
fan can be made with hand tools. If the new fan arriving today won't fit it
might be worth a try since the clutch will fit in my lathe.

Thanks for everyone's help!
