Re: rear end code?

Rick according to my information this is what you have;
AA = 3.55 ratio
W = Warner motive positraction carrier
1 = The Month of February
01 = the 1st day of February
E = Eaton brand
2 = 2nd shift

There are experts on this board that know much more than me, maybe they can verify!
Good luck;
Cary Lewis

Rick -

It's a '71-'75 3.55 Posi, assembled in early April on second shift at Chevrolet-Warren with an Eaton Posi unit. You'll find the casting date on the driver's side of the diff housing, hidden behind the front of the camber strut rod bracket.
