That's a Land Cruiser steering rack, a 4runner one is 950:
44200-35070 - Steering Gear - 2004-2009 Toyota 4Runner | Conicelli Toyota of Conshohock
I went with rackdoctor because across all the models they do, I found exactly one person with an issue. And Rackdoctor replaced it for them free of charge because lifetime warranty. They rebuild only using OEM parts, so I figured it was as close as I was going to get.
I prefer OEM parts, but if it's a replacement I can do myself, is unlikely to strand me on the trail, and the cost diff is more than double, I'm firmly in "good aftermarket" territory. My CVs are OEM, but my brake calipers are NAPA reman for example.
