Friction shims

[Lucky Phil]

Anyone out there know where I can get some of these. They are a thin shim usually zink plated with industrial diamonds embeded  in the plating. They are used these days between cam sprockets and crank cam drive sprockets for the modern engine system that uses friction drive for these components and deletes the keyways.  

What I need are 8mm ID and around 18mm od although the od isnt that critical.

They go under the name of EKagrip or 3M friction drive shims. 3M have bought out EKagip I think. They're one of those things where you need to know the application they are used in and order accordingly as it seems no one stocks them as loose items by dimension.
