### **Pros and Cons of Buying a 1967 1970 Ford C7ZZ-3590-C Shelby Mustang/Cougar Power Steering Pitman Arm (1-1/8")**

#### **Overview**

The **C7ZZ-3590-C** is a power steering Pitman arm designed for **1967 1970 Ford Mustang and Cougar models**, particularly those with Shelby GT350/GT500 or high-performance suspensions. This part is critical for proper steering alignment and function, as it connects the steering column to the steering linkage. Below is a detailed breakdown of its advantages and drawbacks.

---

### **Pros**

1. **OEM Replacement Quality**

- The **C7ZZ-3590-C** is a **direct Ford factory replacement part**, meaning it meets the same manufacturing standards as the original component. This ensures proper fitment, durability, and compatibility with the vehicle s steering system.

- Unlike aftermarket knockoffs, it is less likely to fail prematurely or cause misalignment issues.

2. **Reliability for Classic Mustangs**

- Shelby Mustangs (especially GT350/GT500) and high-performance Cougars often require **precise steering components** to maintain handling and responsiveness. A genuine Pitman arm reduces the risk of play or binding in the linkage, which can affect steering feel and accuracy.

- The **1-1/8" bolt pattern** is standard for these models, ensuring a secure and stable connection to the steering gear.

3. **Compatibility with Restorations**

- If you are **restoring or maintaining a classic Mustang/Cougar**, using OEM parts like this Pitman arm helps preserve the vehicle s original character and value. Collectors and enthusiasts often prefer authenticity in classic cars.

- It fits seamlessly with other **C7-series Ford steering components**, such as the steering gear (C7ZZ-3590-A) and intermediate shaft.

4. **Durability for High-Mileage or Modified Vehicles**

- While not indestructible, the **C7ZZ-3590-C** is built to withstand the stresses of daily driving, track use, or modifications (e.g., lowered suspensions, wider wheels). Its robust construction helps prevent common failures like bent arms or worn pivot points.

- Unlike cheaper aftermarket parts, it is less likely to crack or deform under heavy loads.

5. **Easier Maintenance and Replacement**

- Since it is a **standard Ford part**, mechanics familiar with classic Fords will have experience working with it. Replacement is straightforward, requiring basic tools and alignment adjustments.

- The **universal fit** for 1967 1970 Mustangs/Cougars means you won t need custom modifications to install it.

6. **Supports Steering Precision**

- A worn or damaged Pitman arm can cause **steering wander, uneven tire wear, or difficulty turning**. Replacing it with an OEM part ensures **true alignment** and smoother handling, which is crucial for both daily driving and performance applications.

7. **Long-Term Cost Savings**

- While the upfront cost may be higher than aftermarket alternatives, the **longevity of an OEM part** reduces the need for frequent replacements. This is particularly valuable for high-mileage or heavily used classic cars.

---

### **Cons**

1. **Higher Upfront Cost**

- **OEM Ford parts are more expensive** than aftermarket alternatives. The **C7ZZ-3590-C** will cost significantly more than a generic Pitman arm from a third-party supplier.

- For budget-conscious buyers, this may be a deterrent, especially if the part is not immediately critical.

2. **Limited Availability**

- Unlike mass-produced modern parts, **OEM classic Ford components can be harder to find**. You may need to order from specialty suppliers, eBay, or salvage yards, which could delay repairs.

- Some sellers may charge premium prices due to demand, further increasing costs.

3. **Potential for Counterfeit Parts**

- The classic car market has seen an increase in **fake OEM parts** labeled as genuine Ford components. Buyers must **verify authenticity** (e.g., check part numbers, material quality, and seller reputation) to avoid receiving substandard replicas.

- A counterfeit part could fail quickly, leading to additional expenses and frustration.

4. **Weight Considerations**

- While not excessively heavy, the **C7ZZ-3590-C is heavier than some aftermarket aluminum alternatives**. For high-performance or lightweight builds, this slight extra weight may be negligible, but it could affect steering dynamics in extreme cases.

5. **Installation May Require Alignment**

- Replacing a Pitman arm often necessitates a **steering wheel alignment** afterward. This adds labor costs if you re not comfortable adjusting the steering geometry yourself.

- Some classic cars may also require **tie rod adjustments** or **centerlink modifications** for optimal fit.

6. **Potential for Wear in Older Vehicles**

- If the **steering gear or intermediate shaft** is also worn, replacing just the Pitman arm may not fully resolve steering issues. You may need to address the entire linkage system for long-term reliability.

- In severely neglected Mustangs/Cougars, other components (e.g., ball joints, bushings) may need replacement simultaneously, increasing costs.

7. **Not Ideal for Extreme Modifications**

- While suitable for most **1967 1970 Mustangs/Cougars**, the **C7ZZ-3590-C is not designed for extreme modifications** (e.g., aggressive off-road setups, heavy lifts, or custom suspension geometries). In such cases, aftermarket or custom parts may be necessary.

---

### **Conclusion**

The **Ford C7ZZ-3590-C Pitman arm** is a **high-quality, reliable OEM replacement** for **1967 1970 Shelby Mustangs and Cougars**, offering superior durability, precision, and compatibility compared to aftermarket alternatives.
