Wanted 22mm Wheel Nut for DB9

[zafod]

I have 22mm wheel nuts on my 2007 DB9 - all are fine except for one which is slightly swollen. I can remove this with my 23mm socket but I'd prefer to get a replacement 22mm nut. Unfortunately these are out of production (replaced by 21mm nuts which are torqued considerably higher).

Does anyone have a 22mm wheel nut that's surplus to requirements that they could sell me (I'm in the UK)?

TIA
