Replace those old & broken kick panels with a new concours pair of black plastic panels for XM and XP
New Reproduction Ford Falcon Black Plastic Kick Panels Pair For XM XP Sedan Wagon Ute Van and Coupe.
These may leave a small gap on the base of the A pillar on some XM XP models as the return is not as wide.
Fits XK XL also but you can fit the metal Bracket near the scuff plate.
Quality Plastic so can be painted any colour if needed.
