Went by the paintshop today to check on my car and it appears that the sills and sharks fins on my car were a cheap copy so I am on the hunt for some original parts but I am wondering what the differences are between the turbo sills and the narrow body ones? The Turbo sills seem to have 7 fixings not 6 but is there any other differences? I have a narrow body car so I need to know if the Turbo sharks fins fit narrow body sills ok?
