You'll have to purchase another
badge (which ever one your after) and de
badge the originals so that you have a clean canvas so to speak. To debadge you can use some cotton or dental floss. To do this, put the cotton behind the letters and pull the cotton side to side and apply downward pressure so that you cut through the glue at the back of the lettering. Then rub off the excess glue with your finger and then polish over it once its all gone because otherwise the lettering outline will still be visable. Then just line up your new
badge where ever takes your fancy, peel off the cover on the glue and stick on and hey presto. A re badged rear boot.
