This is 1968 but may help some. My 05D (fourth week of May) 1968 Bird's side view mirror glass has the following etched on it: 5 DMI 8 which I believe stands for May 1968.
My 69 Judge's code is 10 DMI 8 for October 1968 I believe. The car was assembled in January 1969.
I am just assuming that 1967 would have similar dating.
