1969 Dodge Charger bolt size front bumper to frame

I’ve bolt two bolt kits now to bolt the front bumper.

Both are 1/2 with different thread patterns and neither fit.

Does anyone know the correct size and bolt pattern?

Should be 1/2-13 AKA 1/2 NC.... If a coarse bolt doesn't thread in the threads are either damaged or rusty... Run a tap through them....
