* Type of Mirror: If the new mirror is identical to the old one (same make, model, and features), the bracket *should* be reusable.
* Bracket Condition: If the old bracket is damaged, bent, or broken, it definitely cannot be reused. Even minor damage could affect the mirror's stability and adjustability.
* Mirror Mounting: Some mirrors have brackets that are integral parts of the mirror housing, while others have separate brackets that bolt onto the windshield. If the bracket is a separate piece, and undamaged, reuse is more likely.
Before attempting to reuse the old bracket:
1. Carefully inspect both the new mirror and the old bracket: Look for any signs of damage, wear, or misalignment.
2. Compare the mounting points: Make sure the mounting holes and overall design of the new mirror are compatible with the old bracket.
If you're unsure, it's always best to err on the side of caution and use the bracket that came with the new mirror. A new bracket is usually included for a reason and ensures a proper and safe fit. A poorly installed mirror could be dangerous while driving.
