Just use those red and blue plastic ones that come with a new radiator....... LOL.

Mine are standard threaded, hex drive, screw in plugs with some teflon tape.

Not sure about the threads in radiator , but the lines are 5/16” inverted flare

The radiator takes a 1/2 tube nut that is 3/4 -18.......I bought the nut and plan on pluming it and welding it shut. I could not find a plug but one must be out there. This is for a stock radiator.
