Radiator coolant line size question?

Ok. Nothing seem to be working with this thing.
The holes didn't line up, no big deal. I just drilled new ones.
So I went to install the lines, and it's smaller then the 5/16 thread!

Can you get a male/male threaded connector that is 5/16's on one end and smaller on the other? Or should I just take the radiator back?

There is a nut I can take off where the coolant line goes in. Should I take that off and try to manipulate it that way?
