What year is my Magnum block?

I have been having a trouble locating where the date of casting is on my block, which I believe to be a 1993-96 or so, but would like to know for sure.

The harmonic balancer has a scallop on the front.

I know it is a 5.9, but the spot where you traditionally would see a m/d/y on the LA's is not there. It does have one number together - 04039 - could this mean April 3rd 1999? I may be overthinking this but have been striking out on searches online.

Block casting is 5302006

front of block under drivers side head is 92K 360 3748 1 15AB
and below that is 750
