Datsun 240Z Door Mirror Plate: Restoration & Replacement

If you're a proud owner of a classic Datsun 240Z, you know that maintaining the authenticity and functionality of every component is crucial. Among these often-overlooked parts is the door mirror plate. This small but significant piece plays a vital role in both the aesthetic appeal and the safety of your vintage sports car. In this comprehensive guide, we'll dive deep into the world of 240Z door mirror plates, covering everything from their original specifications to restoration tips and replacement options.

Understanding the Datsun 240Z Door Mirror Plate

The door mirror plate, often referred to as the mirror base or mirror bracket, is the component that physically attaches the side mirror assembly to the Datsun 240Z's door. Its primary functions are to provide a stable mounting point for the mirror and to ensure the mirror remains in the correct position for optimal visibility. On the 240Z, these plates are typically made of metal, often chrome-plated or painted black, depending on the original trim level and year. — When Was The Last Blue Jays World Series Win?

Original Specifications and Variations

Throughout the production run of the Datsun 240Z (1970-1973), there were subtle variations in the door mirror plates. Early models might have featured different mounting hole patterns or finishes compared to later iterations. Understanding these nuances is key for enthusiasts aiming for a factory-correct restoration. For instance, some models came with chrome mirror bases, while others, particularly those with sportier trims, might have had black painted bases. The mirrors themselves also varied, from simple chrome-backed units to more aerodynamic "bullet" style mirrors that became popular in the 70s.

Importance of Correct Mirror Plates for Restoration

For a true restoration, using the correct door mirror plates is non-negotiable. Incorrect plates can lead to improper mirror alignment, vibration, or even damage to the door panel. Furthermore, a discerning eye will notice the wrong detail, detracting from the overall authenticity of the vehicle. Sourcing original parts can be challenging, making reproduction parts and careful restoration of existing pieces highly valuable.

Restoring Your 240Z Door Mirror Plates

Many 240Z door mirror plates, due to their age and exposure, often suffer from rust, pitting, or peeling chrome. Fortunately, restoration is often a viable option. The process typically involves disassembly, cleaning, repair, and refinishing.

Step-by-Step Restoration Process

1. Disassembly: Carefully remove the mirror assembly from the door plate. This usually involves unscrewing the mirror from the base. Take note of any seals or gaskets.
2. Cleaning: Thoroughly clean the plate to remove dirt, grease, and any loose debris. For rust, a wire brush or gentle abrasive pad can be used.
3. Rust Removal and Repair: For significant rust, media blasting (like sandblasting or soda blasting) is highly effective. Small pits can be filled with appropriate metal filler if a perfectly smooth finish is desired. Ensure all rust is removed to prevent future corrosion.
4. Priming: Apply a high-quality metal primer to a clean, dry surface. This promotes adhesion and protects against future rust.
5. Finishing: This is where you decide on the final look. For a factory-correct restoration, chrome plating is the ideal choice. However, this can be expensive. Alternatively, you can paint the plates. High-gloss black enamel is a common and attractive finish. Ensure you use automotive-grade paint for durability.
6. Reassembly: Once the paint or plating is fully cured, reassemble the mirror assembly onto the restored plate, ensuring any new seals or gaskets are in place.

Tips for a Professional Finish

• Surface Preparation is Key: The smoother the surface before painting or plating, the better the final result.
• Chrome Plating Specialists: If aiming for chrome, seek out reputable plating shops experienced with automotive parts.
• Paint Choice: Use durable automotive paints. Consider two-part epoxy paints for maximum longevity.

• Specialty Datsun Parts Retailers: Numerous online stores focus specifically on Datsun and Z-car parts. These are often the best source for accurate reproductions.
• Online Marketplaces: Websites like eBay can be a treasure trove for both original used parts and new reproduction components.
• Datsun/Z-Car Forums and Clubs: Connecting with other enthusiasts is invaluable. Members often share leads on rare parts or sell items from their own collections.

Considerations When Buying New Plates

• Material and Finish: Check if the reproduction plates match the original material (e.g., steel) and finish (chrome, black paint).
• Fitment: Read reviews or ask sellers about the reported fitment of the parts. Poorly made reproductions can be a headache to install.
• Completeness: Does the part come with mounting hardware or gaskets, or is it just the plate itself?

Installing New or Restored Door Mirror Plates

Installing a door mirror plate on a Datsun 240Z is a relatively straightforward process, but attention to detail ensures a perfect fit and finish.

The Installation Process

1. Access the Mounting Area: Open the car door. You'll typically find access to the mirror mounting bolts from inside the door panel. Sometimes, you may need to remove the interior door trim panel to gain full access.
2. Remove Old Plate (If Applicable): Unscrew the bolts securing the old mirror plate. Carefully detach the old unit.
3. Prepare the New Plate: If your new plate is unpainted, prepare it for finishing as described in the restoration section. Ensure any mounting holes are clear.
4. Mount the Plate: Position the new or restored plate against the door. Thread the mounting bolts by hand to avoid cross-threading. If using a trim panel, ensure it sits correctly around the plate.
5. Tighten Securely: Use a wrench or socket set to tighten the bolts firmly. Be careful not to overtighten, which could strip the threads or damage the door.
6. Attach Mirror Assembly: Mount the side mirror onto the newly installed plate, securing it with its own screws.
7. Test Alignment: Adjust the mirror to its proper position and ensure it holds steady. Check for any rattling or looseness.

Preventing Door Damage During Installation

• Use Proper Tools: Avoid using oversized or worn-out tools that can slip and scratch the paint.
• Protect Paintwork: Place a soft cloth or masking tape around the mounting area to prevent accidental scratches.
• Correct Torque: Tighten bolts gradually and evenly. If you have a torque wrench, consult a service manual for the correct specification.

Frequently Asked Questions (FAQ)

Q2: Can I use door mirror plates from other Datsun models?
