(Chrysler entered a code for a roof colour on convertibles even though they did not have a painted steel roof)

There should be 2 numbers following this - eg, 11 01, which would stand for the month and day the engine was assembled.
If the number 2 appears after / below the date, that meant the engine was assembled on the 2nd shift of that day.
Hope this helps
