AF Bolt conundrum
I have a 1967 Minor Convertible. It has the old seat belts in it which I don't mind, however I want to add in the rear an extra modern seat belt receiver so I can attach my dogs restraint to it. The current bolt is too short its an inch long, so I need to find a 1.5" one.The bolt has a S symbol on top. I have no idea where to find one. I haven't fiddled with cars for 50 years so I'm a bit out of date. I'm not even sure finites an Imperial bolt or not. Can anyone tell me what type of bolt I would have to order? Thanks

Re: AF Bolt conundrum
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 1¼" bolt, if this is the length of the thread, it would probably work for me.

Re: AF Bolt conundrum
I'm sure it's only the length of the thread when quoting lengths but here's another option. https://www.europaspares.com/seatbelt_b ... ngth_1_1_2

Re: AF Bolt conundrum
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!

Re: AF Bolt conundrum
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.

Re: AF Bolt conundrum
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.
