My 1984 Monte Carlo SS has a stock rear end.
Does anyone know off the top of the head what the specs are for it?
I'm assuming its a 7.5" 10 bolt. no clue on axle spline count. or gear ratio.
i'd like to know so i can start searching for a posi.
Please help

I'll take a look. but i'm sure its stock. the car was owned by an older couple and still had the 305 in it when i got it.
