Power Steering Pump ID help...454 with remote resevoir

[shiner2001]

My power steering pump is leaking, but I'm not sure exactly which one I need to replace it with. The engine is a 454 LS6 from a 70 Chevelle (yes, it's legit, it's the CRV engine code ), but when I search for that car on the parts store's web sites, I don't come up with what I need. It has a remote reservoir and is mounted directly below the alternator on the driver side. It looks like the alternator would prevent me from using one with an attached reservoir or I'd just go that route. Anyway, if anyone can enlighten me as to what I need to be looking for (either a part # or application), that would be mucho appreciated. Here are a couple pictures of what I have...









I found a remote reservoir PS pump on Advance Auto's website, but it looks like the pulley would not stand off from the pump far enough for my application. As you can see in the first picture, there is a couple inches between the beltline and the body of the pump. The backside of that pump looks different as well. I think the guy I had on the phone said that was for a 90 something truck 454.

Thanks in advance guys!
