Thanks for the info guys. Where do you get the info to tell what the DN means. Also I thought the last set of #'s are the date. These do not appear to be the same. Thanks for any other help.

DN is the broadcast code.

Broadcast codes were used in the assembly plants to ID parts for production use. Several part numbers could carry the same broadcast code as changes occured in numbers but not in actual application. This code would show up in the box's on the build sheet (know as broadcast copy).

0304 means the 304 day if year enging in 0, 1970 in this case.
