Rear End Codes

Does anyone have the codes stamped on the rear end of a 1976 L-82 to tell what the gear ratios should be?

Appendix E of the 'Corvette Restoration Guide 1968-1982' by Richard Prince lists the following for '76 and '77 (all positraction)
Code OA - Ratio 3.08:1
Code OD - Ratio 3.36:1
Code LR - Ratio 3.36:1
Code OB - Ratio 3.55:1
Code OC - Ratio 3.70:1
