Hi guys, I'm finding my driver side alternator position can't seem to keep the mustang reverse(counter-clockwise) rotation pump running well at higher rpm. I am looking for a standard (clockwise) rotation pump part number/source. Not looking for the $400 chrome edition. :-)
Anybody have a part reference?

Blueprint's got them:

But are you sure the rotation is the problem? Many people have the CCW rotation water pumps and they work just fine.

It's a one year application .
1985 Ford Crown Vic with 302 engine....
The pulley ( with grooves) is more expensive that the pump.

That's the ticket. I knew the earlier Fords had them.
