I bought a 2000 ford mustang, and since I bought it private sale, I didn't have a Carfax or anything. I knew it had some damage, but while cleaning the interior I found the passenger air bad has been deployed. That's when I went in inspecting the car even finer. I found that the from bumper has been pushed back and crushed the support. What exactly would need to be replaced other then the airbag itself obviously?
