Hello together,(SORRY FOR THE LONG TEXT) I bought an RS bumper, it’s not from Dietrich (unfortunately) or Mattig or something like that. Now I tried if it fits (should you do it before painting). But it doesn’t fit properly, the hole in the middle is missing the two exteriors are there, but it doesn’t fit exactly (a milimeter difference). But it’s not that bad! The sides are bad! They are standing off (driver side 2-3 cm) and I don’t know how to use the intended fittings. I don’t even get to the places where the original bumper was on it.I don’t know any more! Thanks already for your help!
