If I wanted to get all the interior trim to refit a stripped 172 cup, how tricky would it be to find the various pieces? i.e. are any of them unique to the cup model and therefore difficult to find. Things like are the carpets all the same in the cars? what colour seat belts, rear seats, all the moulded bits of plastic, boot floor,etc. Is it all fairly easily available or not really? cheers.
