### **Pros of buying a Mopar 3675670 Grille Extension & Headlight Bezel Molding**

1. **Authentic Fit and Finish**

The Mopar part is manufactured to factory specifications, ensuring a precise fit with minimal gaps or misalignment. This is particularly important for maintaining the vehicle s original aesthetic, especially if you re aiming for a show-quality restoration or a classic look.

2. **High-Quality Materials**

Mopar parts are generally made from durable plastics and metals, designed to withstand weathering, UV exposure, and minor impacts better than aftermarket knockoffs. The molding is likely to resist cracking or warping over time compared to cheaper alternatives.

3. **Easy Installation**

The part is designed to be straightforward to install, especially if you re replacing a damaged or missing grille extension. It typically requires only basic tools (e.g., screwdrivers, trim tools) and may come with hardware or adhesive instructions. No extensive modifications to the vehicle are usually needed.

4. **Compatibility with Other Mopar Parts**

Since it s a Mopar product, it s likely to integrate seamlessly with other genuine Mopar components (e.g., grilles, bumpers, or trim pieces) you might purchase in the future. This can simplify sourcing parts for a full restoration.

5. **Resale Value Preservation**

For collectors or enthusiasts who plan to sell or trade the vehicle later, maintaining original or high-quality aftermarket parts like this can preserve the car s value. A well-preserved grille and headlight area signals attention to detail to potential buyers.

6. **Aesthetic Consistency**

The part is designed to match the vehicle s original styling cues, ensuring the front end looks cohesive. This is especially valuable for cars where the grille and headlight bezels are key to their vintage appeal.

7. **Warranty and Reliability**

Mopar parts often come with warranties or guarantees, providing peace of mind in case of defects. While aftermarket parts may offer similar warranties, Mopar s reputation for reliability is well-established in the classic car community.

### **Cons of buying a Mopar 3675670 Grille Extension & Headlight Bezel Molding**

1. **Cost**

Mopar parts are typically more expensive than aftermarket alternatives. For a single grille extension and bezel molding, the price may range from **$50 to $150 **, depending on availability and seller. This can be a significant investment if you re on a tight budget or restoring multiple vehicles.

2. **Limited Availability**

While Mopar parts are widely available for many models, some specific variants (like the 1970 1971 Demon/Dart/Swinger) may be harder to find in stock. You might need to order from a specialty supplier, which could extend lead times or require patience.

3. **Potential for Overkill**

If your vehicle is heavily modified or you re prioritizing performance over aesthetics, investing in a high-quality grille extension may feel unnecessary. For example, if you ve already replaced the grille with a custom or aftermarket piece, this part might not be compatible or useful.

4. **Weight and Durability Trade-offs**

While the part is durable, it may be slightly heavier than ultra-lightweight aftermarket alternatives. For a classic car where weight reduction is a priority (e.g., for improved handling or fuel efficiency), this could be a minor drawback.

5. **Color Matching Challenges**

If your vehicle s paint or trim has faded or been repainted, matching the exact color of the grille extension and bezel molding can be tricky. Mopar parts are designed for original colors, so you may need to touch up or repaint the molding to achieve a seamless look.

6. **Potential for Misalignment**

Even with precise manufacturing, slight misalignments can occur if the surrounding trim (e.g., bumper, fenders) is damaged or not perfectly aligned. This might require additional adjustments or sanding to achieve a flawless finish.

7. **Environmental and Handling Considerations**

The plastic molding can be prone to yellowing over time if exposed to prolonged sunlight or extreme temperatures. While Mopar parts are designed to be durable, they re not indestructible, and you may need to reapply protective coatings (e.g., clear sealant) periodically.

### **Conclusion**

The **Mopar 3675670 grille extension and headlight bezel molding** is an excellent choice for owners of **1970 1971 Dodge Demon, Dart, or Swinger** who prioritize **authenticity, quality, and long-term reliability**. It strikes a balance between performance and aesthetics, making it ideal for restorations, classic car shows, or maintaining a vehicle s original character. However, the higher cost and potential availability issues may deter budget-conscious buyers or those who prefer aftermarket alternatives.

For enthusiasts who value **factory accuracy and ease of installation**, this part is a strong recommendation. If you re working with a limited budget or plan extensive modifications, you might explore **aftermarket options** (e.g., from companies like **Chrome Craft, ECS, or Speedway Motors**) that offer similar styling at a lower cost. Always compare the pros and cons of your specific project goals before purchasing.
