Plastic wiper nut caps (missing)

[brabus]

Hi , Thanks for your reply ,
But the cap i'm talking about is something similar to this http://www.****************************************************.com/product/986WWC.html?Category_Code=986WIPER .
It comes in a pair, 1 on the left and the other 1 on the right , when you remove it you can see a screw inside it , sorry for my poor description , i try to take a pics of it , but my car is now in the workshop so hopefully someone can help me on this base on my description .


Thanks
