### **Pros and Cons of Buying a GM 510895 NOS (New Old Stock) Steering Gear Box (Pitman Arm Shaft) for 1937-1948 Oldsmobile/Pontiac**

1. **Authentic and Original** A NOS unit means it has never been installed or used, ensuring it is in its original condition with no wear from prior service. This is ideal for restoration projects where authenticity is important.

2. **Reliability and Durability** GM s early steering gear boxes were built to last, especially if properly maintained. A well-preserved NOS part will likely function reliably for many years, assuming the vehicle s steering system is otherwise in good condition.

3. **Ease of Installation** Since the part is new in stock, it should fit perfectly without modifications, provided the mounting points and related components (like the drag link and idler arm) are compatible.

4. **No Unknown Service History** Unlike used parts, you don t have to worry about past repairs, modifications, or neglect. The part comes with no hidden issues related to prior use.

5. **Potential for Future Resale Value** If you plan to sell or trade the vehicle later, a NOS steering gear box can enhance its value, especially among collectors who prioritize originality.

6. **Reduced Risk of Failure** Since the part is unused, there s no risk of sudden failure due to wear or fatigue from prior operation.

7. **Compatibility with Classic Cars** This specific part is designed for 1937-1948 Oldsmobile and Pontiac models, ensuring a proper fit without the need for custom fabrication.

1. **High Cost** NOS parts are significantly more expensive than used or rebuilt alternatives. The price reflects their rarity and condition, which may not be justified if you re on a tight budget.

2. **Limited Availability** Finding a NOS unit in good condition can be difficult, especially for older GM parts. You may need to search multiple sources (auctions, specialty dealers, or collectors) before securing one.

3. **Storage and Preservation Challenges** NOS parts require careful handling to prevent damage from moisture, dust, or physical wear. If not stored properly, they could degrade over time.

4. **Potential for Overpaying** Some sellers may inflate prices due to the "NOS" designation, especially if the part has minor imperfections that aren t immediately obvious. Researching comparable parts and consulting experts can help avoid overpaying.

5. **Not Always Necessary for Restoration** If the existing steering gear box is functional but worn, a NOS replacement may be overkill. In some cases, a rebuilt or high-quality used unit could suffice at a fraction of the cost.

6. **Weight and Handling Considerations** Older steering gear boxes can be heavy, which may require additional effort during installation, especially in tight spaces under a classic car.

7. **Compatibility with Modern Adjustments** Some modern steering systems or aftermarket modifications (e.g., power steering conversions) may not fully integrate with an original NOS unit, requiring additional work or parts.

### **Conclusion**

- **Authenticity is a priority** for your restoration project.

- You have the budget to invest in a high-quality, unused part.

- You want to minimize long-term reliability risks.

- You plan to keep or sell the vehicle as a showpiece where originality adds value.

- You re working with a limited budget, a used or rebuilt unit may be a practical alternative.

- The existing steering gear box is functional but needs minor repairs (e.g., lubrication, minor wear).

- You re unsure about the part s condition despite the NOS designation, a thorough inspection (or even a test fit) is essential before purchasing.

---

### **Recommendation**

1. **Verify the Part s Condition** Even if labeled NOS, inspect the steering gear box for signs of wear, corrosion, or damage. A reputable seller should provide clear photos or allow an in-person inspection.

2. **Compare Prices** Research similar parts (used, rebuilt, or NOS) to ensure you re getting a fair price. Websites like eBay, Classic Auto Parts dealers, and specialty forums can help gauge market value.

- **Rebuilt units** from companies like **Steering Gear Specialties** or **Classic Auto Parts**.

- **Used but high-quality parts** from trusted sellers with service histories.

- **Aftermarket replicas** if originality isn t critical.

4. **Factor in Installation Costs** Ensure you have the tools, time, and expertise to install the part correctly. If not, budget for professional labor.

5. **Prioritize Compatibility** Confirm that the Pitman arm shaft and related components (drag link, idler arm, etc.) are compatible with your vehicle s specific model year and condition.

**Final Verdict:** If you re committed to a fully original restoration and can afford the premium, a NOS GM 510895 steering gear box is an excellent investment. Otherwise, weigh the cost against alternatives to find the best balance between quality and budget.
