well i was wrong. started working on the bumper today and found some rust through spots so I'm back on the hunt. if worse comes to worse, i could patch it if i had to using pieces off my other bumper but i really don't want to do that.
I bet you could patch a rear bumper with a section of a front bumper (maybe).
I never put them side by side, but the groove/detail looks similar. :dunno:
actually the area that is rusted would have to be scavenged off a rear bumper.
