Posi Casting numbers

[don whitehead]

Hi Folks,
In the past 42 years someone put an open rear in my 1960. I am looking for a Posi to put back in. I know there is a large "P" on the housing, but is there any date code and casting number. I looked thru my NCRS guides but did not find anything. The housing seems to be right with the vent.
Regards,
Don

If you have a Noland Adams Corvette Tech. Guide Vol 1 on page 306 there is a
rear axle ID chart.

There will be a date code, casting number, and "GM" casting symbol on the center section housing. The casting number for a 1960 Corvette with positraction should be 3743833. The casting date will be the typical alpha-numeric casting number with letter for month, 1 or 2 digits for the day, and final digit denoting the last digit of the year.
