Pleased you found what you were looking for Bobby.
When I got my BB, both p/u rings were broken.
Looked all over the net, and couldn't find any, anywhere.
Incredibly, the tech. who I took the guitar to for a set-up, who'd never before seen a B/B, had a set of p/u rings among his bits and pieces !
If anybody comes up with a source, I'd be keen to have a spare pair.
