I am converting my stock '64 389 GTO with a clutched fan to power steering. Do I need to change to a notched fan to clear the PS mounting bolts?

No you shouldn't need to. The notched fans were only on 1965 models with factory air conditioning. The notch is to clear the shaft / center of the pulley on the power steering pump, those units had a different power steering pulley. If you have any interference issues, something else is wrong, most likely one of the parts you used.

And I have a 65 with factory AC and don't have the notch but also clear the PS pump, its close but still enough room to not be concerned. This is on a 66 block but I assume the mounting/alignment is the same.

Thanks for the info!
