TR Lane roll bar thead sizes?

[db418BHP]

Anybody know the thread size in the harness mounting point.

I need to order some 'eyes' as the ones supplied with my new Sabelt harness have a larger thread.

Does a standard seatbelt bolt fit? Thought they were a universal size 7/16 unf

TR Lane have confirmed that the threads are 7/16 UNF.
So what have Sabelt provided with their harness? The eye bolts are a larger thread.
