Tools You'll Likely Need:
* Screwdriver: Likely a Phillips head, but possibly a flathead depending on the screws holding the glove box in place.
* Pliers: May be helpful for manipulating the lock mechanism.
* New Glove Box Lock: Ensure you get the correct replacement part for your 1968 Impala. Parts stores or online retailers specializing in classic car parts are your best bet.
* Possible additional tools: depending on the state of the existing lock and its components, you may need small pry tools, needle nose pliers, or even a small hammer.
Procedure:
1. Remove the Glove Box: Open the glove box fully. You'll likely find screws holding the glove box to the dashboard. These are usually located on the sides or the bottom edge of the glove box. Remove these screws. The glove box should then pull forward and out. Be gentle; some parts may be brittle after years of use.
2. Access the Lock Mechanism: Once the glove box is out, examine the lock mechanism. You should see the lock cylinder, a latching mechanism, and possibly some linkage connecting it to the glove box door. You'll need to disconnect these components. This part is highly variable based on the lock's condition and design. Pictures of your specific lock would be extremely helpful.
3. Remove the Old Lock: This is where things get tricky. The old lock may be held in place by screws, clips, or just friction. Carefully inspect the assembly to determine how the old lock is secured. You may need to carefully pry or wiggle it loose. Take your time and avoid using excessive force to prevent damage. Take photos as you disassemble as this will help you during reassembly.
4. Install the New Lock: With the old lock removed, carefully examine the new lock to understand how it fits. Align the new lock with the existing mounting points and install it in the reverse order of removal. Ensure that the latching mechanism and linkages are properly connected and working correctly.
5. Reassemble the Glove Box: Carefully put the glove box back onto the dashboard and reattach the screws you removed earlier. Make sure everything fits snugly and the door closes and locks properly.
6. Test the Lock: Try the new lock to make sure it works correctly.
Important Considerations:
* Take Pictures: Before you begin, take detailed pictures of each step of the disassembly process. This will be invaluable when you reassemble the glove box.
* Parts Compatibility: Make absolutely sure you purchase the correct replacement lock for your specific year and model Impala. There's some variation within model years, so be precise.
* Patience and Precision: This task requires patience and a careful approach. Rushing the process can lead to broken parts and unnecessary frustration.
* Shop Manual: A shop manual is your best friend for this type of repair. It will provide detailed instructions and diagrams that are far more specific than a general guide.
If you're uncomfortable performing this repair yourself, it's always best to take your car to a qualified mechanic or restoration shop. They will have the experience and specialized tools to complete the job safely and efficiently.
