Some call it a posi but it seems to work like a limited slip to me.To test if it works ,you have to be spinning the wheels at about 10 mph. When one wheel slips the other will engage.To get both wheel to spin in the same direction. But in most cases that's not possible.so another way is th spin one wheel really hard and fast. You should here a little clunk and both wheels should spin in the same direction. In non lock mode both wheels will spin in the opposite direction. This info is not gaurantee. Gm does odd things at times. You should always double check.

Also olds bravada should all be gov locked and I think I saw somewhere that they are the 8.5 but my neighbor that runs the local pick a part said that's not true. I havent looked that deep into it just when i was cruising the web.
But the bravada axles seem more plentiful and better priced. Car-part.com also helps when your on your search!!
