### **Pros and Cons of Buying a 1973 1987 Chevrolet/GMC FleetSide Rear Inner Wheel Panel (Lower) Part Number OER T71123**

#### **Pros:**

1. **Original Equipment Replacement (OER) Quality** This part is designed to match the original specifications of your vehicle, ensuring proper fit, function, and durability. It avoids the potential issues that can arise from aftermarket parts that may not align perfectly with the vehicle s structure.

2. **Reliability and Longevity** Chevrolet and GMC FleetSide trucks were built to last, and using an OER part helps maintain the vehicle s integrity. The lower rear inner wheel panel is a structural component, and a high-quality replacement ensures it will hold up under normal use without premature failure.

3. **Aesthetic Consistency** If you re restoring or maintaining the truck s original appearance, an OER part will blend seamlessly with the rest of the body. Aftermarket parts may not match the exact shape, finish, or fit, leading to visible inconsistencies.

4. **Warranty and Support** Purchasing from a reputable dealer or manufacturer often comes with a warranty, providing peace of mind in case of defects. Some OER parts may also be backed by the original equipment supplier, offering additional assurance.

5. **Prevents Rust and Structural Damage** The rear inner wheel panel is susceptible to moisture, road salt, and debris, which can lead to rust and weaken the wheel well. Replacing a damaged or corroded panel with an OER part helps prevent further deterioration and maintains the truck s structural integrity.

6. **Easier Installation and Maintenance** Since it s designed for the specific model, installation is typically straightforward, and mechanics familiar with classic trucks will be more comfortable working with it. This reduces the risk of installation errors that could compromise safety or performance.

7. **Resale Value Preservation** For collectors or those who plan to keep the truck long-term, using OER parts helps preserve its value. Potential buyers or restorers will appreciate the use of genuine components, especially in well-documented builds.

#### **Cons:**

1. **Higher Cost** OER parts are generally more expensive than aftermarket alternatives. The price reflects the quality, authenticity, and often the limited availability of original or reproduction parts for older vehicles.

2. **Limited Availability** Depending on the year and condition of your FleetSide, finding an exact OER part may require sourcing from specialty suppliers, salvage yards, or online marketplaces. This can add time and effort to the replacement process.

3. **Potential for Counterfeit or Low-Quality Parts** Not all sellers of OER parts are legitimate. Some may offer "reproduction" or "new-old-stock" parts that, while labeled as OER, may not meet the same standards. Researching the seller s reputation and verifying the part s authenticity is crucial.

4. **Weight Considerations** Original steel panels are heavier than some modern or aftermarket alternatives (e.g., aluminum or lightweight composites). While this isn t a major drawback for most FleetSide trucks, it s worth noting if you re considering weight reduction for performance or fuel efficiency.

5. **Rust and Corrosion Risks** Even new OER parts can rust if not properly treated or installed in a clean, dry environment. Older parts may have hidden corrosion that isn t immediately visible, so inspecting for pitting or weak spots before installation is important.

6. **Installation Challenges** If the surrounding area is heavily rusted or damaged, replacing just the panel may not be sufficient. You might need to address adjacent components (e.g., frame rails, wheel wells) to ensure a proper fit and seal, adding to labor costs.

7. **Time-Consuming Restoration** If the panel is part of a larger restoration project, sourcing and installing OER parts may slow down progress. This is particularly true if you re restoring multiple panels or working on a truck with extensive rust damage.

### **Ending Conclusion:**

The **OER T71123 rear inner wheel panel (lower) for 1973 1987 Chevrolet/GMC FleetSide trucks** is a high-quality, structurally sound replacement that aligns with the original build standards of these vehicles. It is ideal for owners who prioritize authenticity, longevity, and the preservation of their truck s value. However, the higher cost and potential challenges in sourcing or installing the part may make it less appealing to those on a tight budget or seeking quick, low-cost repairs.

For most serious restorers, collectors, or owners who want to maintain their FleetSide s integrity, the **pros outweigh the cons**. The investment in an OER part pays off in reliability, appearance, and long-term performance. If budget is a concern, carefully weighing the options such as high-quality aftermarket alternatives or salvaged original parts can help strike a balance.

### **Recommendation:** - **Buy the OER part if:**

- You re restoring or maintaining the truck s original condition.

- You value structural integrity and long-term reliability.

- You can afford the higher cost and are willing to invest in quality.

- You have access to a reputable supplier (e.g., classic truck specialty shops, eBay verified sellers, or parts auctions like Copart or IAA).

- **Consider alternatives if:**

- You re on a tight budget and can find a high-quality aftermarket part that fits well (e.g., from manufacturers like **Rust-Oleum Restoration Products** or **EZ Off-Road**).

- You re restoring a heavily rusted truck and need to replace multiple panels sourcing multiple OER parts may not be practical.

- You re willing to source a **salvaged original part** from a clean wreck, which can be more affordable while still maintaining authenticity.

Ultimately, the **OER T71123 is the best choice for purity and performance**, but always verify the part s condition, source it from a trusted seller, and ensure proper installation to maximize its benefits.
