i have a 12 bolt posi from a 71 chevy 1/2 ton truck in a 66 carryall, the problem with it is a chatter when i turn left ,after it has been driven several miles {say 150 miles or good and warmed up?}right turns seem to be ok? can new clutch plates be bought at gm or? and should that cure the problem ? i have not torn it apart yet to inspect the plates ?what should i look for on used plates ? thanks mike
