Lambretta Headset (handlebar) lever pivot bolt, 8mm oversize with washer and nyloc nut, stainless steel, MB
MBP0094K
It is common to find that the holes on your clutch lever housing and light switch housing have ovalised through years of wear.
They can be hard to find so rather than trying to source replacements you can drill the hole out to 8mm and use these stainless steel pivot bolts.
The bolt comes with a plain washer and a nyloc nut.
