5carguy = Based on the logic of reading the casting dates above, it looks like your date is 2-42-7, which obviously doesn't make any sense. That is an interesting date. What is the year and SPD of your Cuda?
Look at the part number on the box - that's not a 71 part.
That is a box dated the 242nd day of 1977. The box part number is incorrect for a 71 car, it has obviously been changed out. Looks like the dating of these boxes changed between 1971 and 1977.
