Some 4.56 gear questions!!

Ateam, are you refering to me or Joe?

if you are refering to me, I already a little over a weeke ago jacked the car up and spun the tires and came to a conclusion as to what gear I have.

I was "TOLD" I have a sure grip....but I can't honestly say exactly what I have.

I know when I turn one wheel...the other wheel turns the same direction as the one I am turning and with no slop/play.

I know before I bought the car that the previous owner had just had are local performance drive train shop go through the hole rear end and rebuild it....and I know it has 4.56 gearing but as to if there as any other goodies in there, I do not know
