I bought a 54 chevy truck 3100 and it had a open drive rear end . I took the rear end to a driveline shop today and im trying to find out what year it is . Im think its either a 551st or 55nd series rear end . they told me it has 4.11 gears and the number on it is AG206 . Im hoping its the 2nd series rear end so i can run the 3.38 gears . heres a pic of the rear end.
