Start by finding out the rear end type. In your case it'll probably be the 8.5" corporate 10-bolt. From there, find the codes stamped into the axle and take a look here for links to what they mean.
Rearends got changed a lot through the years, so the ratio from the stamped code might not be what's in it now. To find the ratio now in it you can take a look here.
