HO52 found in field is it any good?

[spuddy98]

I used to have a 69 c10. Owned and drove it from 1987 to 1999 or so. Did some towing with it and dreamed of bigger brakes. So I acquired a HO52 Eaton rear end from a friends wrecking yard. It was in a '72 C20 Cheyenne auto as I remember. Just found it in my pasture. Guess its an Eaton. Is this rear end worth saving? Should I disassemble it and sell the Pig? Its prolly worth $30 for scrap. Been sitting where it is out doors for what? 27 years or so since I brought it home. Any suggestions? Might be more work than its worth but i always hate to see good things go to scrap.
Thanks
