I've tried all the known dealers I can think of.
Shawspeed, Puma Speed, Birbeck, Burtons, Mountune and even the good old ebay. Ebay had a company advertising a set of glyco bearings but their dimendions thit not match the bearings in my engine.

I've not contacted Burtons though only browsed trought their site.
I'll send them a mail.

Thank you.
