I bought an airbag cover for my FJ cruiser because mine was damaged although the airbag was not deployed, just the cover cosmetically was damaged. I am a pretty competent mechanic. I easily was able to remove the airbag assembly from the steering wheel. My problem is the cover is held in place with 4 specialized rivets. What is the recommended way to remove the rivets and what should I replace them with? Any help would be appreciated.
