Default Dewitt's radiator oil cooler question

I've bought the radiator that has both the EOC and TOC fittings for my C5 Z06 2001 corvette and am now realising I should've bought the one without all the fittings. What can I use to block off all the holes? Does anyone know the threat size and pitch of the 4 holes in the radiator for the oil cooler connections? Hopefully I can find some bungs that fit in them.

Just leave the plastic plugs in them that came in them, nothing will leak out.

Thanks for your input but there were no plastic plugs that came in them. I found out one side is M18 x 1.5 so I can just use a pair of exhaust bung plugs.

I'm still trying to figure out the thread and pitch for the right hand side/ drainage side, its smaller than M18

Never saw one that didn't have plugs in the holes to keep trash out during shipping and handling.

But, yes, you could just leave them open.

Me either. It it were me, I'd blow compressed air in one port, then switch and blow thru the other port, back and forth. Hopefully this will clear any debris, if any, out of there. Then plug, or connect whatever...
