72 Blazer - Power Steering Conversion

[PDXk5]

I'm in the process of ordering parts for my winter project of converting from manual to power steering. I was ordering parts from Classic Industries when I learned that they no longer carry the quick ratio 4x4 power steering gear box. Dang.

Any recommendations? I checked LMC and Truck stop - neither carry the quick ratio. I was ideally going to stick with all GM parts but want to get the parts ordered so I'm ready fairly quick. Anyone have a source to recommend or have familarity with this after market company?

Is this a direct bolt in? Any issues? Anyone used this before? Any help will be greatly appreciated.
