'86 Rearend question

Hate to break it to you, but the axle code for a Trac-lok rear is 3L08.

The L is the letter which indicated the limited slip differential.

I don't know what P refers to. What did this rear end come out of?


It's a limited slip differential, not a spool or locker. Posi is a GM term, so ford wouldn't use it on theirs. Their name for it is "Traction-lok"
I can't find use of a "P" in any of my Ford shop manuals. M, Z, Y, etc., no P. imp
