Help identify a 8 3/4 differential

Hey guys was doing a bit of cleaning and found this what I believe to be 8 3/4 differential. If I remember correctly It came out of my a body 8 3/4 rear that I installed a posi unit.

Seems like a lot of guys are wanting highway gears so I figured why have a 2.73 posi? Idk was just curious about it. I may just scrap it

Before scrapping it you may want to offer it up here for free +shipping, someone may want to weld them spider gears up and fart around with it until it breaks.
