I have a 1970 leaf-spring 6-lug 3:07 posi, which is "TPO 0422". I decode this as:
- TPO=CA 10 3.07 posi
- 0422=April 22
What is the meaning of CA vs CE?
At first I thought it might be leaf spring rear suspension vs. coil spring rear suspension, but I see the same with K-series so this is ruled out.
