I will have a word with Tony michaels the ACOC Chairman, Tony advertised good quality reproduction spare wheel lock down Four eared nut many years ago in ACtion Magazine. ( I Will try to find advert in relevent back issue of ACtion)
If the club had some done then the ACOC can get another batch made and despatch to club members via Acedes Spares.
Will keep you and Forum posted.
In the meantime, this very subject was definitely discussed in depth about 18 months ago on the club Forum, Not sure if it was under General, Ace or Cobra section, tend to think Ace & Cobra....
