Oil filter adapter gasket?

[Slonaker]

My new crate 350 needs an oil filter adapter for the screw-on oil filter. I was going to just buy a new one if they weren't too expensive, but the auto parts store didn't have one. I now plan to use the old one off the 305. The folks at O'Reilly sold me a Fel-Pro oil cooler kit when I asked for an oil filter adapter gasket, and said that is the only way they sell the gasket.

It came with a lot of o-rings that I don't need and 2 gaskets. My plan was to use the gasket that looked like the one that came off the old engine, but the adapter was installed on the old block without a gasket.

Of the two included gaskets, both have holes that line up with the bolts, but neither of them is shaped like the adapter. Which of the gaskets do I use?

Would NAPA or someone have a new part with the gasket? Is it actually supposed to have a gasket? Does the kit I have even have the right gasket, or is the included gasket for a different shaped part that is used by an oil cooler?
