The pump that is on the engine now is new from Advance Auto with the dual bolt pattern. The problem going with the small bolt pattern becomes finding a 1 1/2" spacer and a fan both with the small bolt pattern. One posibility may be drilling the pulley that I have to match the the dual pattern pump flange.
