The other part is a blank, which you would install if you had neither the grab handle or the sunglasses pocket.
Well. My apologies for failing to help.
I do not have access to the EPC currently, but when I searched the part number of the handle these last couple of days, I found that EU site with pictures. If you look carefully at the picture there is no indication that the size of the attachment is different between the two. The "clips" look the same size.
I hope there is a different way to attach than to have to cut the metal...
