if you only see 1 mark its most likely worn out.the irocs have a 9 bolt thats for shure a posi but i just took my 9 out put in a 7-5/8 with a powertrax and love it.my 9 used to leave 2 good marks but it slowly died out lol

You have to pull the inspection cover and look. That's the only way to tell if you indeed have a positraction unit.
