Does anyone know on a 496HO oil cooler, what the factory fittings are? They appear to be a -8 AN, but perhaps they are something else that just looks the same? I think the factory adapter fittings threaded into the cooler are a 1/2" inverted flare, but I'm not sure what the male end that is exposed is? See attached picture of the fittings.

Also, does anyone happen to know if the remote mount oil filter base center return fitting is a -8 AN?

Thanks guys!

Cooler is -8AN
