Thanks for the information. Just one thing, is the length of the bolt measured from the top of the bolt cap to the end of the thread or just the thread? The length of my thread is 1" & I saw on the link you sent, they do a 1ΒΌ" bolt, if this is the length of the thread, it would probably work for me.

I'm sure it's only the length of the thread when quoting lengths but here's another option.

Great idea. I have a 1969 Convertible. I had rear inertia reel seat belt fitted just so that my dog could be safely restrained. He loves it!

She cant wait!

It is always the length of the bolt (or set screw) shank - which may be part (or all) threaded. Counter-sink screws are different, of course.

The type of head used for seat belt retention will depend upon the seat belt anchorage.
The large head type bolt (shown in the photos above) is used when you have a shouldered spacer between the end of the belt and the floor/pillar of the vehicle.
The shouldered spacer allows the end of the belt to rotate. There is usually a wavy washer between the end of the belt and the shouldered spacer to stop any rattling of the end of the belt.
A small or standard headed bolt should not be used with the shouldered spacer as the head of the bolt does not fully cover the shouldered spacer aperture in the end of the belt.
The captive nut/plate goes under the floor or behind the metal seat belt support. The small hole in the plate is for a small securing bolt which will stop the plate rotating when the bolt is tightened.
