Need to know the size and pitch of the seat belt Bolt

I hope that I have some gurus chime in before I order, I am replacing the seat belts on my son's 75 F100. He wants the race Style that snaps in eyelets rather than the ones that get bolted down to through the floor. My ? Is does anybody happen to know what the size of the bolt as I don't have them and what the pitch is?

I was also thinking 7/16" but wasn't sure of the pitch. I found several companies that have the eye bolts, but all it says it that they are 7/16" but never mentions pitch.

Factory bolts are probably Torx, maybe T25?

You will likely need a 1/2" drive ratchet and lube as the threads are exposed to the elements under the truck.
