Yes I know what you mean. I'll have another go. This is on a defender with air conditioning and a winch. However, it's not welded on so if it bolted on it must be able to come off. Thanks for your replies.
Ahh yes and there lies the problem. I can't remove the grille to get at and withdraw the bumper bolts because the A Bar prevents it. Chicken and egg situation hence my query - the solution will be very obvious when we get sight of the instructions!
