Detroit locker

Being that it’s an older Detroit unit and it has wire tie/lock provisions on the bolts, chances are it was an old nascar unit.

Doesn’t really matter now though. I wonder if any or all the guts are shared with the common Ford Detroit lockers.

Might want to take it guy that does Circle Track rear ends. Or a 4x4 rear end guy. They use them too.

I believe the springs in them help determine how quick or hard it locks. So you should have it checked out to see if it fits what you want to use it for. It could be setup for a pretty brutal engagement.

Nowadays they offer “soft” lockers or different models of them.
