N.O.S. GM P/S box

[special-K]

This is a 2wd power steering box for up to '75 or '76 I believe. That's what I remember from when I ordered it. I guess it's up until metric fittings. Anyway, these were not cheap from GM, like $350. There are modern alternatives and they are rebuildable, so I was wondering how much it matters about N.O.S. as far as value.

I had ordered it for a '71 K/20 with sloppy steering. But I decided to part a Blazer I had and used that steering box. Many many years later my '72 K2500 needed a steering box so I dug this one out of the box. All these years later I discovered the parts guy ordered the wrong steering box, a 2wd version. The N.O.S. pitman arm I also ordered was the correct 4wd part.

So I'm asking to see if I'm wrong thinking it's nothing all that special as far as N.O.S. goes (ironically, since it's so important) and I might as well use it on my project and sell the rebuilt for whatever.

I'm looking for opinions as well as a what it's worth.
