I think other Yamaha's used this part too:
I'm looking all over for one of these. Anyone want to sell one, or loan a n.o.s. one?
I know a guy that remakes rubber parts if some old yamafans want to do a group buy.
It would be even better if anyone has a n.o.s. one to copy
I was kind of thinking that maybe 3d printing might be an option??
