I can't find my rpo sticker so I dont know. Either money didn't, or it's just worn out and become a one wheel peel.

Edit: it's an 89

Yes they all have a clutch type positraction. It's called a "Trac Lok".

If yours is spinning one tire.... STOP doing that. You can over speed the spider gears and explode the Posi unit destroying the entire diff.

New clutches are Dana Spicer PN 707018X. About $60.00

I did it once, and later wondered who put the single tire mark in front of my house. Did it a second time to confirm. Thanks for the part numbers, I'll either have to wait for next summer to do the job or talk to my friend who has a lift and a heated garage.
