Nobody has been working on the car, found one on the driveway near the rear passenger side door, the other a few weeks later in the driveway. Have looked at all four doors, rear hatch and hood for anyplace they might fit and found nothing. I assumed they were isolators but have no idea where they came from.Well, they're gonna be bumpers / panel isolators for sound & gap. I've seen them used on fenders where the hood contacts it closed. So, add a little detail. Anyone been working on the car? Where around it were they found?
