I have an 89 lx with carbureted 306 and posi only works when turning left. I was wondering because I want to replace posi how to tell or maybe u guys know if isa 8.8 31 or 28 spline. it has a 4 lug wheel if that matters

pull a axle and count the spines. then you will know. if it is a stock rear it will be 28s

I believe its stock so thank u . I want to order parts so I can put right back together

Ifs its a stock trac-loc just spend money on the clutches ~$70. Should be the same for 28 and 31 spline units.

i was going to just buy the whole trac lock. how hard are the clutches to change?

uedlose

They use to be $69. Guess they have gone up. Been a few years since I bought a set.

$75 at 5.0 resto. Carbon discs are $108.
