The lower bearing and plastic retainer are under tooling by Rare Spares at present and hopefully samples will be ready for testing soon. If approved supply should be early 2015. The top bearing is available now, and shows in the parts book as a replacement part, but doesn't mention about the rolling over of the edge as originally done. Both bearings were originally supplied from overseas but when production stopped recently they have had to be remade by Rare Spares.
