I bought a nice rust free diff and this j&j irs came with it. I’m wondering if anyone has seen one sold lately and what it was priced at. Found an old motortrend article.
Interesting setup from a long time ago. If the center is a 63 and stock it wouldn't matter because it will still fail. It would be interesting to see if any custom work was done to the diff, that might make a difference- but 63-4 gears and posi's were bad. That would also be a narrow case, requiring now obsolete shims. If you are selling the center I buy cores for $250.

Just cleaned up the diff and will post details in for sale section.
