what is this tag? what does it mean?

I was doing a tire rotation today, and i came across this tag on the frame that appeared to be either welded or stamped on.

The letters "JA" seemed to appear on there, they are sideways BTW. Can anyone shine some Light?

Just the frame code. Denotes what body went on what frame. Pretty much just a part number.

I'm pretty sure that stands for Jack Ass
