Okay im really getting pist about this, I have posi, but only one *****ing wheel spins! Somone please solve my dilemma
You dont have posi. Posi is a GM thing. If only one wheel spins though, you have an open differential and not "limited slip."
well that goes to show that you dont listen to pot heads who think they know what theyre talkin about. okay next question how much would it be for locked differential.
GHETTO! If you're only spinning 1 wheel, you do not have T-lok. A locking differential is different from a limited slip differential. A limited Slip T-lock diff is what you need. If you do upgrade, get urself a set of 3.73 gears too. https://www.stangstore.com/Merchant2/merchant.mv?Screen=CTGY&Store_Code=S&Category_Code=V6 T-lok is just fords version of POSI, they are the same thing.
