new doors for 72 have threads in holes for door panel clips?

[vettedad61]

1972 C10 restored, the new doors are after market repos purchased new, the problem is that when I went to install the door panels the clips will not fit into the holes on the door because the doors have threaded nuts attached on the back side?
I checked my old doors and the don't have threaded nuts?
I checked the receipt and the doors say 1972 doors?

has anyone run into this and what did you do?

I'm guessing either drill them out or find smaller diameter door panel clips but they will need a big head to still attach to the door panel
