833 numbers/date code

[Bobfish]

CP, Im trying to figure out what the deal is with my 833OD that was "modified" to go in my 'Cuda. ( I was not involved in its build) Can you id these #'s for me? R. side on pad PP8335309- I know the plant and 833 but how do I figure out the 10,000 day code (when did the 10K start!?!?!?) Also C89129. On the L. side C95664Z and 2-25 (this is where the date code is on another 833OD I have that is dated 6-78) Thx, Bob

My calendar stops at 4720 which is June 30, 1974.

You can count the days from there up if you really need to know I suppose.....
