N.O.S. 2wd P/S Box

[special-K]

This is a GM power steering box I bought years ago for a '71 and it's a 2wd unit. Here's the thing...My truck was a K/20 and I was having wandering problems and the junkyard box I got when I converted to P/S was sloppy,so I ordered this. Meanwhile I bought a Blazer for parts to swap the TH350/NP205 into another Blazer with 3psd/Dana20. I decided to try that steering box first and it was fine,so I never used the new box. Fast forward 20+ years and my '72 K2500 needed a steering box. No problem,I have a brand new one in mothballs,right? Well,I pull it out and turns out they sold me a 2wd steering box. The only 2wd I have is my '67 project built on a rolling '71 frame I bought from Hart Rob with a rebuilt steering box. So...what would the value if this be? You can't get them now,it is absolutely brand new,and I believe it listed for $300+ when I bought it

Still have this Steering box. Still curious what it's worth.

The rest of the story is,I also bought a pitman arm at that time. It came unboxed with a tag wired to it,so I could see that was the right part. Took both and painted then gloss black before installing,went to put the pitman arm on the sector shaft and WHAT???
