Default Posi or no Posi?

With my 57 up on jacks I turn the driver's side rear wheel and the opposite side wheel turns the same way. Does this mean Positraction or open rear end?

All a Pee is going to tell you is - it COULD have a posi.
It could also have a posi without having a P
The only for sure way to tell is to remove the fill plug and look inside
