Which version?
If it is one with a rubber bush in the yoke (the bit with the bearings in), I have toyed with the idea of having an interference fit bush turned at work, freeze-fitted and then freeze fit a stub. I'd then use the current c/b weights that have internal O rings. This would be for a second deck/spare as I won a very cheap, very new, export 2-3 years ago in EPay, before people got wind of how good they are.
Tonearm lift/cueing platform?
