Does anyone know how the front grille badge is held on and how you take it off.The new badge iI have to go on only relies on a sticky pad to hold it on ,do you think this will be sufficient?

The original badge is held by the same sticky pad.
You can take it off using a screwdriver.

The new badge will hold just fine using this stick pad.
You can use glue to stick it firmer but than you would not be able to take it back off.
