Rear seatbelt bolt size??

[Bentley T6]

Does anyone know the correct bolt thread for the holes for seatbelts on the c-pillar in a T6 Kombi?

I had the rear belts removed when I had a caravelle rail put in and wanted to plug the holes left with a bolt and lashing eye to hang things. From what I’ve looked at it might be a 7/16th unf thread but does anyone know if this is correct?

Thanks

I think your correct on that size... its been a while since I was in the trade but that rings a bell with me.

AFAIK still 7/16 UNF after all these years.

Thanks. Got one and thread starts but is a little tight, didn’t want to force it incase the thread isn’t quite correct.
