The **Dodge Chrysler Mopar 3730973 Birdbath Hood Wiper Linkage Transmission Pivots** (commonly referred to as the "birdbath" assembly) is a critical component for 1972 1980 Dodge and Chrysler vehicles with manual transmissions. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

---

### **Pros of buying a 3730973 Birdbath Assembly**

1. **Direct Fitment and Compatibility**

The 3730973 assembly is designed specifically for 1972 1980 Dodge and Chrysler vehicles equipped with manual transmissions, including models like the Coronet, Charger, Challenger, and Dart. It replaces a complex cluster of parts (hood wiper linkage, transmission pivots, and related brackets) in one package, ensuring proper alignment and function.

2. **Simplified Installation**

Unlike sourcing individual parts (such as the transmission pivot brackets, hood latch rods, or wiper linkage), the birdbath assembly comes pre-assembled. This reduces the need for precise machining or custom fabrication, making installation faster and less prone to errors. Most mechanics can install it in a few hours with basic tools.

3. **Reliability and Durability**

The assembly is constructed from stamped steel, which, while not as robust as modern castings, is designed to handle the stresses of manual transmission linkages and hood mechanisms. Many original birdbath assemblies lasted the lifetime of the vehicle if properly maintained, and aftermarket replicas are often built to similar standards.

4. **Cost-Effective for Repairs**

Purchasing the assembly as a single unit is typically cheaper than buying each component separately. For example, sourcing individual transmission pivots, hood latch rods, and wiper linkages from multiple suppliers can add up quickly, whereas the birdbath is sold as a complete package at a lower total cost.

5. **Preservation of Originality**

For enthusiasts restoring classic vehicles, the birdbath assembly is a straightforward way to maintain or restore factory-correct functionality. It avoids the need for aftermarket modifications that could compromise the vehicle s authenticity.

6. **Widespread Availability**

The part is widely stocked by Mopar dealers, specialty classic car parts suppliers, and online retailers (e.g., eBay, RockAuto, or dedicated Mopar forums). This makes it easy to source, even for rare or hard-to-find models within the 1972 1980 range.

7. **Reduces Risk of Misalignment**

Manual transmission pivots and hood linkages require precise alignment to function correctly. The birdbath assembly is pre-aligned, reducing the risk of improper fitment that could lead to transmission slop, hood binding, or wiper linkage issues.

---

### **Cons of buying a 3730973 Birdbath Assembly**

1. **Potential for Wear or Damage**

Like any used or aftermarket part, the birdbath assembly may exhibit signs of wear, rust, or bending, especially if purchased from a salvage yard or a seller with unclear history. Inspecting the part for cracks, deformation, or excessive corrosion is essential before installation. Some aftermarket versions may not be as robust as original parts.

2. **Limited Customization**

The assembly is not adjustable or modular. If the vehicle s hood or transmission tunnel has been modified (e.g., for a different engine or suspension setup), the birdbath may not fit perfectly without additional machining or fabrication. This can add unexpected labor costs.

3. **Compatibility with Modified Vehicles**

Vehicles with aftermarket manual transmissions (e.g., non-Mopar units) or heavily modified hoods may require custom adapters or modifications to accommodate the birdbath assembly. Always verify compatibility with the specific transmission and hood setup before purchasing.

4. **Quality Variability**

Aftermarket birdbath assemblies can vary in quality. Some cheaper replicas may be thinly stamped or poorly aligned, leading to premature failure or installation difficulties. Original parts (if available) are generally more reliable but may be harder to find and more expensive.

5. **Installation Challenges**

While the assembly is designed for ease of installation, some vehicles particularly those with extensive rust or frame damage may require additional work to clear the area around the transmission pivots or hood latch rods. This could involve removing rusted panels, adjusting brackets, or modifying surrounding components.

6. **Potential for Misalignment with Other Systems**

The birdbath assembly interfaces with the hood latch, wiper linkage, and transmission linkage. If these systems are worn or misaligned elsewhere, the birdbath alone may not resolve all issues. For example, a failing hood latch or wiper motor could still cause problems even with a new assembly.

7. **Cost of Replacement Parts**

If the birdbath assembly fails prematurely (e.g., due to poor quality or improper installation), replacing it again can be costly. While the part itself is relatively inexpensive, labor costs for reinstallation add up, especially if the vehicle is on a lift or requires additional disassembly.

---

### **Conclusion**

The **3730973 Birdbath Hood Wiper Linkage Transmission Pivots** assembly is a practical and cost-effective solution for restoring or maintaining manual transmission functionality in 1972 1980 Dodge and Chrysler vehicles. Its primary advantage lies in simplifying a complex repair into a single, manageable component, reducing labor time and potential errors. For most enthusiasts and mechanics, the benefits outweigh the drawbacks, especially when purchasing from a reputable supplier and inspecting the part for quality before installation.

However, the cons such as potential quality issues, limited customization, and the need for careful inspection highlight the importance of sourcing the part wisely. If the vehicle has been heavily modified or if the surrounding systems (hood latch, wiper linkage, etc.) are degraded, additional work may be required to ensure a seamless fit.

---

### **Recommendation**

1. **Source from a Trusted Supplier**

Purchase the birdbath assembly from a well-known Mopar dealer, a specialty classic car parts retailer, or a seller with verified positive reviews. Avoid salvage-yard parts unless you can thoroughly inspect them for damage or wear. Aftermarket replicas from brands like **Mopar, ECS, or Jegs** are generally reliable.

2. **Inspect the Part Before Installation**

Carefully examine the assembly for:

- **Cracks or bends** in the stamped steel (especially around pivot points).

- **Rust or pitting**, which could weaken the part over time.

- **Proper alignment** of the transmission pivots and hood linkage rods.

- **Smoothness of holes** for bolts and pins (no stripped threads).

3. **Verify Compatibility**

Double-check that the birdbath assembly matches your specific vehicle model and transmission type. Some variations exist between Dodge and Chrysler platforms, and aftermarket parts may not fit all applications perfectly.

4. **Prepare the Vehicle for Installation**

Ensure the surrounding area (transmission tunnel, hood latch, and wiper linkage) is clean and free of rust or damage. If necessary, replace worn bushings, brackets, or linkages to avoid future issues.

5. **Follow Installation Instructions Carefully**

Refer to a **factory service manual** or a detailed online guide (e.g., from **Chilton, Haynes, or a trusted mechanic forum**) to ensure proper alignment and torque specifications. Incorrect installation can lead to binding or premature failure.

6. **Consider a Professional Installation if Unsure**

If you lack experience with manual transmission repairs or hood mechanisms, consult a mechanic familiar with classic Mopar vehicles. While the assembly is designed for ease of installation, improper fitment can cause long-term problems.

7. **Keep Spare Parts on Hand**

If you plan to work on multiple vehicles or anticipate future repairs, consider keeping a spare birdbath assembly or individual components (e.g., transmission pivots) in stock for quick replacements.

---

**Final Verdict:** The **3730973 birdbath assembly** is a **highly recommended** purchase for restoring or maintaining manual transmission functionality in 1972 1980 Dodge and Chrysler vehicles, provided it is sourced from a reliable supplier and installed correctly. For most users, the convenience and cost savings justify the purchase, while the potential cons can be mitigated through careful inspection and preparation.
