Hi Luddite
I only changed fasteners as they had zero markings and where soft stainless
I prefer marked stuff on what I deem safely items like brake pedals and footrests.
The other thing I'm not 100% happy with is the rearsets pictured don't look like they have bearings in where they bolt to the swinging arm pivot.
(they may have but look like bushes unlike the ones I fitted which came from same seller but a few months ago)
they may have just made neater covers for bearings
Regards
Rick
