I've finally managed to fix my sunroof (at least temporary).
After dismantling the whole thing, I found out that the roof was no longer attached to the sliders. I managed to find one of the nuts and bolts, but not the other

instead I used a standard but and bolt.
I'd like to get a replacement nut (so I can adjust it) but don't know if I can actually get these anywhere, expect, maybe Main Dealer, if so do they have a part number, and anyone know it?
Thanks in advance
