Strangest thing found in your A body???

So I get my demon home last summer and proceed to put new carpet in it. Upon taking the rear seat out and the remainder of the old carpet, I find these signatures. I guess a couple of line workers had a little time to spare.

What a small world. I think Dave Heller runs/ran a transmission shop outside of Defiance, OH. I know the name from somewhere. It seems like he was running a nasty Mopar drag car at the time I was referred to that shop for parts. That was probably around 1997 or so.
