Next time you are in Aldis (and Lidl), grab a box of their assorted grommets...they have blanking grommets in there and fit the smaller holes in the floorpan of our Mopars perfectly! £3 a box....bargain!!
The ones from Aldis look and fit the little holes (up to 1") that have factory blanking grommets in. Just fit them in upside down and they look original!!!
