Hi, my 1979 Oldsmobile Regency 98 is starting to rust through the top part of the rear bumper. I was thinking I would have to replace the bumper? I haven't had any luck finding one. Any ideas where to get one? I know these are notorious for rusting through & therefore may be hard to find. Thanks

Is something like this repairable? Picture of my bumper
