Wishbone ball joint thread size?

[The OC]

Hi guys - Does anyone know the upper wishbone ball joint thread size? Looks to be 14mm diameter but I can't get an M14 nylock nut onto it..

Thanks in advance!

Can’t be sure off the top of my head but it might be 9/16” UNF.

In case anyone needs it.... the answer is M14 fine (1.5mm thread pitch). All sorted now.

And I would have said 9/16 unf too, but maybe that was a very long time ago

Another vote for 9/16" until I checked my copy of the 1995 build manual which say M14. Oh the joy of an old imperial 7. Metric and imperial fixings all over the place!
