Wemoto uk are currently having some sort of sale on various sizes of pro-bolts. Looking through they did have black m6 x20 aluminium button head screws- just the job for the paso. Comes with a washer ( I assume it's black plastic) and a collar ( which I guess I will glue in place.
Pack of 10 for £8. Never used pro-bolt but they are very good by all accounts.
If yours are a bit past their best (mine are) this could be a chance to get some nice replacements.
Now does anyone have a source for the slightly larger pair at the top of the body work!!
Best regards

No pictures in the sizes we need, but you will find both M6 and M8 fairing screws in various lengths in both stainless and black (presumably anodised aluminium) here :

Just checked as I thought I didn't get such a good deal
Their m6x20 are £1.79 each so £17.90 for 10. Plus no black plastic washer and no shoulder.
Looks like the wemoto deal is good. Cannot find a black m8 button for the top two screws on either site though!
