I have a 89 RS with a 2.8L and indeed it has a 3.42 axle ratio. But no it did not come with posi. it does have a limited slip though, which is essentially the same thing as posi.

Check RPO codes located under the console lid for code G80 which indicates the Limited Slip option (aka Posi). Not many people special ordered these model cars and GM did not add a lot of options to keep the price low.

Odds are you have the peg leg version, I have one in my driveway right now. I bet mucho money that NO V6 car got a posi.
