I had a freak accident today and the rear bumper of my 93 honda civic got ripped off. What happened was that I was backing my car in the parking lot, and the iron chain from the loading dock of a giant truck got stuck between the bumper and the rest of my car. As I tried driving forward, the chain ripped off the bumper from my car. So can I just have the bumper reattached, or do I need a new bumper? How much would replacing the bumper cost me (if I do need one)? I just looked on ebay and found I can get a rear bumper for my car for about 0. So can I buy one and reattach it myself? Thanks
