I need two of the seat belt mount nuts for the inner rockers, it's basically a nut welded to a 1"x4" peice steel, they are the ones in the center tunnel and inner rockers.

Alternatively, does anyone know what the size and thread pitch is? Could just make it up my self if I could find a supplier for the nuts.

Thanks
Kevin

I believe they are all 7/16" fine thread. US standard.

I doubt they are u.s spec. No other fastener on the car is. I will measure one today.

I may have some of these....I'll look tonight.

Bruce,

Side note, but I think Bowlsby or someone has covered this in a thread before, which I don't have on hand at the moment. But I believe they said that seatbelt bolts had to be standardized in the U.S. so even if every other fastener is metric, the seatbelt hardware is not.

Interested to see what you find though.

I just made up a set for my brothers car.
The nut is a 7/16 '' x 20 thread.
The factory bolts screw right in no problem.
Get yourself some 1x4x3/16 steel drill a hole in the center and weld a 7/16x20 nut on it then weld it to the inside of the inner long. I don't have pics handy but I plan on taking some next time I'm over helping him.

Hope this helps.

yep, thanks for the info, the seat belt hardware is all 7/16x20 confirmed with a tap and die. Would have never thought they were an SAE thread as the REPA bolts are graded as 8.8

Cheers
Kevin

You're wrong. They're functionally 7/16" UNF. International standard.
