Need rear axle enlightenment

Was checking codes in a glove box on a 67 1/2 ton and found one with a listing of JO4aa SP44 G87 power lock with 3.54 gears.Then it specifically listed apart number of 3903545. So I am assumming it was some kind of special order rear end. I understand the positraction but what is the differences between that and NO-spin and Power Lock ---codes below

G80-Positraction
G86-No spin
G87-Power Lock
