What size is the thread for the seat belt mounting bolts?

 

I have done search without success.

 

I need to get some eyelets so I can fit my harnesses. I plan to use the existing belt mounting holes at the side by the door and what where the mounting points for the buckle end of the rear seats were.

What size is the thread I need?

 

Thanks

Thats what I thought. Must be an industry standard.
