Door Scuff Plates
Removal of the scuff plates is simple, simply remove all visible screws from the top of the plate, and pull up gently to remove. on AU Falcons, there are no other tabs, however the scuff plates themselves can be brittle due to age

suitable replacement screws for the scuff plates have been identified as 10G X 16mm Metal Screws. Note that galvanised, non-tapping screws are recommended to prevent rust and unnecessary damage to plastic tabs respectively, however self-tapping screws can be used, provided care is taken with screwing in the screws required, to make sure they go in straight rather than boring a new hole in the plastic tabs underneath
BA or BF Falcon scuff plates can be fitted to an AU Falcon with minimal modification, making it appealing for aesthetic reasons, broader aftermarket support (specifically the installation of custom badges) or simply due to a larger availability of intact factory parts as the AU Falcon parts become older and harder to come by. The following information can be used as needed for retrofitting a B-series scuff plate to an AU Falcon

Follow the instructions below to replace the front door scuff plates of your AU Falcon with ones from a B-series Falcon
Locate the rear-most plastic tab, and gently pry it from the steel underneath
This may break the part due to the plastic tabs having been exposed to the elements. A Trim removal tool is recommended for the best chances of removing the tabs in one piece
