Hope it's not the same here but I'm always finding parts listed online but when you go to buy them, you're told they're now NLA.

I presume this is the crank end cover, I find the problem with it is that when you find a new one, after searching all over the place, a month or so on the bike and it's scratched or peeling. That's why I never fitted my new one. I'd like to see some carbon ones for sale, might hold out a bit longer - but I do prefer the look of the chrome finish on the original one. Maybe a steel, hard-chromed one would be the best solution. With a carbon half cover.
