Did some additional research and found some good pictures online. It looks like, luckily for me, there are no spot welds in this area. Its some sort of gasket between the inner and outer panel.
In other news, I love when packages show up at the house. Hopefully this fixes my oil leak for good.
Bought from here, for $150+/- shipped. I was super excited to see that it does in fact come in a Honda box and is stamped P72 etc...
