They should be the same on each side. Do you have the steel pegs or the bolt-up rubber assemblies...there have been several sizes of those...WD 16H are certainly different from mid-50s Dominators for example.
There is a difference of 31mm between the hole centres on the two types of hangers.
Ted, if your contact has any of the longer civilian type I would appreciate details as I need one to make up a pair. The shorter WD type seem to require contortionist effort to effectively apply brake pressure, certainly for my size elevens.
I find it is possible to rectify bent ones with a lot of heat and brute force, the longer one was a good 20º out of alignment originally. Still needs a slight tweak but nearly there.
Hello Pete . They are definitely the shorter Wd Type at least the loose one's
anyway ! he does have a vast stock of nos Parts bsa norton triumph ect next time i go over i will ask if he has the longer type for you
