Have tried Repco and S/cheap but they dont have anything close to fitting.
Any ides how I can get these off, or where I might find a catalogue of the nut styles available? Don't mind buying a complete new set, as long as I can get the adaptor to fint the current ones.
The common ones have the adaptors that insert into the nut, but mine is the opposite

Any advice much appreciated.
Cheers,
Dave
