Question about seat belt anchor bolts

[Gone]

What is the right size and thread for the seat belt anchor bolts for a 1970 Super Bee? I've tried 7/16 x 1 inch coarse and fine threaded bolts..neither work. Is it a smaller size...or a special bolt?

I'm sure someone has the correct bolts. They really are a specialized piece.

That was to ensure DOT compliance.
No funny bolts.
