Hi, I recently bought a Fiat punto and although it is in great condition I have a problem with both Wing mirrors. The previous owner must have either knocked into something on both sides or had that done to his car. Both mirrors have snapped plastic on the inside. They both have a snap just in front of a plastic sort of nut. The owner has just had them balancing on the car by using the rubber on the mirror arm onto the car. I need this fixing asap and have been looking at replacement units. The problem is though that it is actually the snapped plastic that is the issue, I could remove both mirrors and replace but the snapped plastic would still be there. Any help would be great and sorry for my lack of knowledge on the parts.
