I bought this from Summit Racing: 

Summit Racing SUM-340104 Saginaw Power Steering Pump.

I think it should be an ok replacement.  After I posted I went out to the garage and dropped the low pressure hose into a bucket and completely drained the fluid.  I then ran more fluid through the system until it ran clear.  I reconnected it all and filled the reservoir and then turned the wheel lock to lock a dozen or so times to bleed the system.  I live in north East PA so its too early to run the car for a little while yet.  But the fluid in the reservoir is much cleaner that before - it took on a brown tint but with a flash light I can see the silver bottom of the pump.  First time around it was all brown murky mess – so I don’t think I fully flushed it well.  

I am hoping that the old fluid was a different consistency of my PS fluid and it was not releasing the air bubbles from concentration – if that would be case than the fluid was filled with bubbles like a bottle of soda.  Well, I am hoping anyway – I am new to this and just learning.

Of all the new pulleys I installed the PS pump is the only one that looks slightly out of alignment.  I might try and shim it a little to get it perfectly plumb – but that’s a big project that I am not getting into today.
