Mounting 1” ball mounts? Dash holes are M6. 1.0

Just an FYI the Bronco mounting bolts behind the dash screen on the 2025 Badlands Sasquatch are M6 1.0

I ordered some Ram Mount 1” tough balls to mount my handheld GMRS radio and discovered this. I read somewhere that they were standard 1/4” 20 bolts and that’s incorrect

anyway hope to save someone else the trouble.
