75/77 throttle lifter arms

[Loki]

I'm trying to build up a spare set of carbs for my 77 CB750F1, yes it is an F1 NOT an F2!
The part I'm missing is the throttle lifter arm for cylinders 3 and 4, Part of the assembly 16035-392-004 but none of the individual parts are numbered, somebody somewhere must have one of these gathering dust in a nice to have box?

Found some on Ebay when I was looking for something else from a really nice guy called Martin who goes by Oggy, also welcomes contact if you're having carb issues.
