Rear End

My car original came with a 3.42 open rear end, the previous owner said he changed out the 3.42 differential and installed a '78 3.73 posi differential. The other day I had the car on jack stand and when I spin the driver rear tire the passenger rear tire spins in the opposite direction, I never had the cover off to look inside but I assume its all stock gm stuff, I was told that my clutches are worn out? I don't understand because, if I am at a dead stop I can squeal tires and if I manual shift it from 1st gear to 2nd I can chirp the tires
