Default 8.2 Build date

I have an 8.2 from a yard that I'd like to know the year it was made. It has oil fed axle bearings and XC P335 stamped on the front of the passenger tube. According to Wallace Racing, XC is 2.78 posi for years 69-72. "P" is for Pontiac plant. 335 is month and day? 335/365? Is there a way to know the year?

Bottom right corner of pumpkin when viewed from the rear is the date code. Sounds like you got it with the K211
