Hi Fred,
I don't know if this will still be a useful lead. Bill Hart had spare KVA MK3 front and rear clips some years ago when we called in to see him. I don't know if he has still got them or if he has sold them. They were painted in Gulf livery and he had them because he had changed his car to a MK1 body. He doesn't seem to still be a member of the enthusiasts club but if you send me a PM with your email I will send you his contact details. He is based in Telford UK.
Cheers
Mike
