Axle Codes 1967-1968
Short answer: On the Billing History card, the axle-ratio sales code appears in box 74 (1967) or box 37 (1968). The codes are the same both years:
| Code | Ratio |
|---|---|
| C | 2.56:1 |
| D | 2.78:1 |
| E | 2.93:1 |
| F | 3.08:1 |
| G | 3.23:1 |
| H | 3.36:1 |
| K | 3.55:1 |
| P | 3.90:1 |
| S | 4.33:1 |
Don’t confuse these sales codes with the two-letter code stamped on the axle tube (decoded separately).
