A couple of weeks ago I crushed a section of the chrome rear bumper with a trailer with a bad coupler . Anyway, it didn't cause any body damage, just bumper damage. I found a bumper of the local Craigslist, but it doesn't have sonar, and I do. Am I crazy to think I can drill out the holes with a metal drill bit and put the sonar sensors on the new bumper? Are they easy to remove and reinstall? Anyone with some experience here, some advice would be greatly appreciated.
