G 5/8 - 14 is a most likely a BSPP thread. IMHO.

Any leads on where to find a 5/8-14 BSPP to 1/2 NPT or JIC adapter?

This is where I purchased quite a few fittings.
Here is an example of what you may need.
I would recommend that you don't cut off the fittings on your radiator. They may not a have a heavy enough wall to Hold up to pressure after an internal threading operation.

They also sell NPT pipe couplings designed (forged) for hydraulic applications.
That link is to a male BSPP adapter. You need a female BSPP to NPT.

I don't believe the thread is 5/8-14 BSPP because of the flare taper at the end.
Try this link for info on identifying the thread. They carry just about anything you can buy for businesses.

Right on Eric !
I missed the taper when I looked at his photo.
The easiest thing would be take the radiator to someone that makes up hydraulic hoses.
