my dads EB got backed into gently today , and has pushed the rear bar downwards slightly , i had a quick look to see if it can be adjusted back up somehow but i cant find a way, the bumper will lift up by hand to where it was , only a cm or 2 , or have i over looked something that allows adjustment?
any suggestions?

remove it and refit, that way you can check if any mounts or anything have been damaged.

they have a fibreglass reinforcement which are held in by screws should be 5 screws.the screws always break and the bumper drops a little if thats happend pull put the moulds the chrome ,grey or red strip and put some self tapper screws in and put the strip back in.I used to repair bumpers before and nearly all ea-b-d falcons had the screws broken.

that seems to have done it , for now anyway , thanks guys
