Hummmm...I get the funny feeling that somehow by helping you Vamp_77, I will end up being at the butt end of a joke..... 
That being said, on the right hand side of your differential, on the cover bolt should be an identification tag with the axle size (ie 7.5, 8.8), gear ratio and stamping number.
Hope that helps.
