Factory Original 69 Camaro Hurst Shifter

[Hotrodpaul]

I need help with the datecode on my 69 Camaro SS 396 Hurst Shifter. It looks to be original with the 3138 number stamped on the side, rubber molded inserts where the rods attach, Chrome round shift handle, etc. The date code reads "39D12K" and the car was assembled in late April. I assume the 9 means 1969, D is April, and 12 is the 12th day, but what does the "3" and "K" mean? I can post pics if needed.

Thanks, Paul
