Anodising swinging arm end caps ?
 

On my '92 851 the gold anodised end caps on the ends of the swinging arm and also the chain adjuster plates are looking a bit faded/worse for wear. Anybody had them re-anodised ? How do you get the right match for the gold colour ? Best companies used ? What form of anodising is best (hard anodising, sulphuric acid anodising - don't what the difference is myself, just what i've seen on the web)

Just got brand new ones, from pro twins, godstone. rear end looks mint now.dave.

How Much Did They Cost ??
