Default Re: 12 Bolt Posi Rear End Date Code

Generally speaking:
Pumpkin casting date - 3-4 weeks before the car was built
Axle tube stamping dated 1-3 weeks before the car was built.

I know of a 10B car and its rear is dated 9/30, 10D car is dated 10/22.
My 11A car is dated 10/16 on the tube and 10/8 on the pumpkin.

Earlier 12 bolt rears seem to be harder to find.
