Need advice on installing an oil filter adapter

They make them both ways. one with an external hex on the outside, and one with the 3/8" square on the inside...

The problem with the external hex drive is the hex is thin and sometimes hard to keep the socket from slipping off...

The threaded adapter thing has a noticeably deeper hex on the Magnum engines compared to an LA one I was using before. I'd just grab one from a junkyard, as easy as changing the oil filter on a pickup truck lol
