".....All of the critical information about your rear gears would be on a sheet metal tag, nominal 1/2" x 3" held in place under one of the bolts securing the gears/cover....."

That's true for some rear ends Roger provided you're lucky enough for the tag to still be there.

On a lot of the GM and Mopar rear ends the gear ratio and application data is stamped on one of the axle tubes.....in very small font and usually a PIA to find and read.
