Im going to answer my own question:
First of all, this is definitely a dealer-only part. I got the part today, as the dealer actually had it in stock. The parts counter guy actually knew exactly what i was looking for when i started describing it. My guess is that this happens often. NB: If you are leaking power steering fluid, check the fitting on top of the power steering pump.
The good news is that the new part has been modified to eliminate this faulty collar, which was clearly a bad design.
Oh, and it cost $82.00
