AI Prime 16HD mounting hole specifications?

[a hill]

Does anyone know the specs for the mounting hole?

I plan to make a custom mount. The goosenecks are good, but the attachment clamp is terrible.

I’m hoping to try photography style arms and wood or metal floor light style.

I’ll be sizing it myself tomorrow, and am hoping others can post what it is so I can confirm.

Thanks for your consideration, and if anyone else is interested in doing something similar let me know, I’ll share my results.
