CAV, when you read this maybe there is a market for RECONDITIONING of pre ADR25A sports wheels. Basically get the mob that is building you new wheels to use the earlier wheels as exchange? That way you are rebuilding existing stuff and you aren't selling new stuff so any legal issues avoided. If the repro 3mm wheels are say $350 each, i'm sure anyone here would pay the same to get their old worn out or even broken 5mm wheel made as new? I've got a few in the shed including broken examples. I'm sure Greg has some too.
