Are you looking to fit it on top of the perch, or underneath (as on the RT3).

So what items do you have and what items are you missing?
Do you have the lever and the base for the lever?
If so, then I believe all you need are some spacers and mounting screws.
Does the photo I linked help you in any way?

Looking at the photo in your post from back in June it appears you have almost everything needed except for one spacer and screw. So I’m not sure what you are looking for.

yes I have everything except the screws or bolts and collars and or spacers.
the old photos show I have one collar and screw, 
the other side appears to take a smaller collar and shorter screw.
If someone had the hardware for both sides I would take it, that way I would likely have everything correct.

I understand now. Your goal is to find correct Yamaha parts to replace your missing spacer and screw.

Otherwise you could simply measure the gap and make your own spacer using whatever length screw is required.

Good luck with your search. I will let you know if I ever come across them. Did you ever reach out to DEET as suggested in one of your earlier posts?
