Differental typing

[Yeller90]

Is there a tag or physical difference in the diff that visually tells you what differential type you have? or is it easier to jack it, up turn a wheel and see if the other one goes same direction or opposite? On GM cars there used to be a tag that said use limited slip fluid that was a dead giveaway when at junkyards.
