the right turn signals

Anyone know where i can find the proper stems to fit into the headlight mounts for front turn signals? I bought a set that was supposed to fit, the stud is too short and wrong diamater...and the ones that came with bike, on fairing, are the same....thanks

I think most Japanese turn signal stems from the day are 10mm.
It might help to post photos of the stems you've tried & where you're trying to attach them.
I guess the problem could be the stems or the mounting points. ???
