I have just been out to have a look and I don't know what you mean either? what colour are your blocks? Have you actually pushed them with a finger? if you do, and they flex, they are therefore the same sheets of flimsy plastic that are on mine
I can't see the end of my cills as I have mudflaps fitted. (cills are the long curved panels below the door stretching from wheel arch to wheel arch. Are we talking about the same place?) . I do have flimsy (well what do you expect from Mitsubishi
) black plastic shields at the back of the front wings , visible when you open the door. I presume they simply fill the gap.
Mine is a 15 reg so may be different.
