Car in neutral, jack 1 wheel just off the ground & bear hug it & if it turns forward easily it is not a sure grip. If it turns a bit with alot of grunt then it is a sure grip & confirms you are in neutral & roughly confirms how tight the sure grip clutches are live every 24 hour block of time like it's your last day on earth

Generally early ones were clutch type and later ones were cone type... although past parts swapping could change that. I don't know a good way to tell short of pulling the pig.

NO other limited slip differential name is as easy to say or as identifiable as Posi-Traction. Sure Grip Traction Lok Twin Grip Anti Spin Detroit Locker Saf-T-Track..... They all are correct factory brand names.

That or if you have the car up on the hoist and in neutral, with a suregrip both tires will spin the same way when you turn one tire by hand. With an open diff, one will spin backwards.
