Sorry about this but there seems to be some confusion about the cam belt kit part number that is good for my 1994 williams 1.
Using my number plate and giving it to Renault they reckon 7701469775
But RPD reckon 7701471866 and you seemed to think that number was correct too.

Any ideas why there is this confusion?
Because I have found a genuine 7701471866 part quite cheap.
