5. **Maintenance Requirements** Like any mechanical component, the zipper may require occasional lubrication or adjustments to maintain smooth operation, especially if the vehicle is frequently used or exposed to harsh conditions.

6. **Mismatched Condition** If you re restoring a heavily damaged or rusted Challenger, the zipper might still require additional work (e.g., cleaning, repainting, or sealing) to match the overall condition of the interior.

7. **Limited Customization** If you re looking for aesthetic or functional upgrades (e.g., tinted glass, different materials), this OEM zipper won t offer those options. You d need to pair it with aftermarket modifications.
