I agree that it isn't going to just be a cake walk to make, there is going to be some trial and error as far as making a form and getting it shaped correctly, but when you get the form down it will be as easy as it could possibly be. As far as drilling into the bumper to install it on the bottom, I was actually thinking that small zip ties run through the original grill locking tab slots and then through the part of the grill material that is broken over along the bottom would be a great solution for retaining it along the bottom. I am talking about the really tiny zip ties that you would probably never notice but would be strong enough for the task at hand.
