I've had a few of these aftermarket 36 grills over the years. They aren't as nice as an original, but function the same. They are installed from the back of the grill shell, so the grill shell overlaps the perimeter of the grill and the shell opening defines the visible shape (it's kind of deceiving).
It doesn't fit a 36 shell very well. I tried one. Also no opening for the clips on the two inner vertical stainless pieces.
