No axle code on yours. Fender tag axle codes (A31, A33, A34) are only denoted on 'performance' ratios; i.e. the A33 code designates 3.54 Dana , A34 is 4.10 Dana (as stated by Chryco) and A31 is 3:91 8 3/4. You do have a very cool and unusual color combo: Tawny Gold ext/gold int/yellow side moulding.
