oil pressure spring plug

Thanks guys. I think I found a Dorman part number, but nobody locally stocks it. Most things i’ll look up, end up saying expansion plug in the description. I don’t want to try and shove the wrong thing in there, and realizing that I need to drive it in backwards from normal, I’m probably just going to throw the MP high-pressure kit in my cart next time I order something from Summit.
inquiring minds want to know, Dorman part # ?
