Oil pump gasket?

They are inside the pan where oil pumps belong. Those big block mopars are some strange beasts with their exposed pumps and such. :D

There wasn't a gasket in my 360 magnum and I didn't use one when I rebuilt it.
personally, I like it being out where a guy can change it, or rebuild, or go bigger w/o pulling the pan. Oil filter up front , easy to get to.---to each his own-
