THIS THREAD from 2006.
For reference, it should be stated that the thread on the studs is 7/8" BSF (7/8"-11tpi). All threads for the divided rim studs are right hand thread.
On Canadian CMPs, wheels fitted to either left or right side of the vehicle have Left or Right hand thread 5/8" UNF (5/8"-18tpi) Lug Nut and Studs for each side of the vehicle.
British vehicles that use these style of wheels (and also towed equipment like 25Pdr Guns and No27 Limbers, even those made in Canada) have BSF thread Lug Nuts and Studs in LH and RH 1n 5/8"BSF (5/8"-14tpi).
These wheels freely interchange between Cdn or UK vehicles (and towed equipment), but the lug nuts and studs are particular to the vehicle.
