Hello Valentino, I sadly only have one 529 end link and it was probably polished in the past to fit a 18mm lug width.
So I don't think it's fair to sell it.
It's currently on my Constellation, but this week I should get a better fitting endlink.
If this works out, you can have my 529 endlink for free, if you are interested.
Here a picture of it.
