### **Pros and Cons of buying a Lincoln D7LB-17C837-AWB (1977-79 Rear Bumper Filler Set, LOC-509DG)**

1. **Original Fit and Finish** This is an OEM (Original Equipment Manufacturer) or high-quality aftermarket part designed specifically for 1977-1979 Lincoln Mark IV/Mercury Grand Marquis models. It ensures a proper fit without gaps or misalignment, maintaining the vehicle s aesthetic and structural integrity.

2. **Durability** The bumper filler is made from sturdy materials (likely fiberglass, plastic, or reinforced composite) that are resistant to impact damage, UV fading, and general wear over time. Unlike cheap aftermarket parts, it should last as long as the original bumper assembly.

3. **Aesthetic Consistency** The part is designed to match the factory styling of your vehicle, preventing a mismatched or "bolted-on" look that cheaper alternatives might produce. This is particularly important for classic cars where authenticity matters.

4. **Reliability** Since it s a widely available part (especially from reputable suppliers like LOC or Mopar), you can trust that it will function as intended without premature failure. Many of these parts are tested for compatibility with the original vehicle systems.

5. **Ease of Installation** The part is pre-cut and designed to fit directly onto the frame rails, reducing the need for extensive modifications. Most owners or mechanics can install it with basic tools, though some may require a helper for alignment.

6. **Resale Value Preservation** For classic car enthusiasts, maintaining original or high-quality aftermarket parts helps preserve the vehicle s value, especially if it s kept in showroom condition.

7. **Warranty Coverage** Reputable suppliers often provide warranties (e.g., 1-5 years) against defects, giving you peace of mind in case of manufacturing issues.

1. **Cost** This is not a budget-friendly part. Prices typically range from **$100 to $250 **, depending on the supplier and whether it s new or refurbished. For a classic car owner, this may be a significant expense, especially if multiple parts are needed.

2. **Limited Availability of Suppliers** While not rare, you may need to order from specialty auto parts stores, classic car suppliers, or online marketplaces (e.g., eBay, RockAuto, or LOC s website). Availability can be inconsistent compared to mass-market parts.

3. **Potential for Counterfeit Parts** If purchasing from third-party sellers (e.g., eBay), there s a risk of receiving a knockoff that doesn t fit properly or is made from inferior materials. Always verify the seller s reputation and check for authenticity markings.

4. **Installation Challenges** While straightforward, some owners may find the process tricky, especially if the bumper or surrounding panels are damaged. Rust, misaligned holes, or warped metal can complicate fitting. Professional installation may be necessary, adding to the cost.

5. **Weight Considerations** Fiberglass or plastic bumpers are lighter than steel, which can affect handling slightly. However, for most classic cars, the difference is negligible unless you re performing extensive modifications.

6. **Maintenance Requirements** Like any exterior panel, the bumper filler may require occasional cleaning (e.g., removing road grime, waxing) to prevent discoloration or cracking over time. Neglecting maintenance can lead to premature aging.

7. **Compatibility with Modifications** If your vehicle has aftermarket modifications (e.g., lowered suspension, custom bumpers), the OEM filler may not align perfectly. In such cases, a custom or aftermarket alternative might be needed.

### **Conclusion**

The **Lincoln D7LB-17C837-AWB (1977-79 rear bumper filler set)** is a **high-quality, reliable choice** for restoring or maintaining the original look and function of your classic Lincoln or Mercury. Its **precision fit, durability, and aesthetic appeal** make it ideal for enthusiasts who prioritize authenticity and longevity. However, the **higher cost and potential installation challenges** may deter budget-conscious buyers or those without mechanical experience.

If you re restoring a classic car and want to preserve its value and appearance, this part is **highly recommended**. If you re on a tight budget or dealing with a heavily modified vehicle, you might consider **aftermarket alternatives** (e.g., fiberglass kits from companies like **Fiberfab** or **Bumper Works**), though these may not match the OEM look as closely.

---

### **Final Recommendation**

- You re willing to **invest in restoration** and prioritize **long-term durability and resale value**.
