rear diff. id question

I have a 8.8 rear from an '86 Mustang GT. The tag denotes 3P08. Both wheels spin in the same direction when jacked up. What does the "P" mean on the Ford 8.8 diff. I know it isnt a limited slip or open rear.

never seen a "P" on one
only "L"
spinning together in same direction means its a limited slip
or posi traction as maybe the "P" stands for

I don't think Ford ever made a 3.08 LS. You defintely have 3.08 gear ratio there. Not sure what the P is either. Could be part of a date code

Just call your local ford dealer and give them all the #'s and they will tell you everything about it even the " P "

I doubt it. Most people who work at dealerships are surprisingly clueless.

It's definitely not posi traction, as that's a GM term.

It must mean limited slip. But I've never seen P before, only L.
