I'm a bit confused.
The only Fiddle I know of is a SYM.
It's Kymco competitor would be the Like.
Not seeing any on ebay for the SYM, but I didn't do a real deep dive since I don't know what other names it uses.
Beyond that SYM OEM parts tend to come only from SYM in the U.S. unless ya can get Cam Purvis to poke around.
Barring a lucky find I'd be inclined to just get it done locally or do it yourself. It's not impossible, just somewhat annoying the first time ya do it (hint buy twice as much material as you think you'd need).
