59035 pump is not available anywhere that I can find. Only fits the B and early 2B engine fitted with the fan clutch.
Pumps for fixed fans are available.
I'm not currently in need of one, but looking at a rebuild as the only reasonable solution.
Yeah, unfortunately I have the pump with a fan clutch. Fortunately, I don't need a replacement yet, but it is different from yours and unobtainium so far. Probably have to rebuild it when the time comes.
