V = name of the plant that made it, I can not think of it right now.
125C = Ford Tr. '87-91 F250 3.55: 10.25 NL
Ford Tr. '87-91 F350 3.55: 10.25 NL
55 = 3.55:1 Ratio (There is a 3 under the bolt head)
10 2 = 10.25" Ring Gear
8K04 = Mgf. Date Oct 04, 1988
These tags tell you a lot more than the code on the door.
