I have this ABM top yoke kit which I believe was originally intended to convert early SS bikes with Clip-ons to traditional handlebars.
I purchased it used and never fitted it.
The fork holes are 50mm
The top nut hole is 24mm
Offset 30mm
It comes with all the fixtures and fitting shown which give several options for handlebar position.
I'm sorry, but that's all I know about it.
