Below is a detailed breakdown of the advantages and disadvantages of purchasing this part.

---

### **Pros**

1. **Authentic, Original-Spec Components**

- The part is **New Old Stock (NOS)**, meaning it was manufactured during the original production run (likely in the late 1930s or early 1940s) and has been stored in original packaging.

- Unlike modern reproductions, it will **exactly match** the original build specifications, ensuring proper fitment and function.

- Many restorers prefer NOS parts for **historical accuracy**, especially in concours-level restorations.

2. **High Quality and Durability**

- Chevrolet s early steering components were built to last, with **precision-machined gears, hardened steel shafts, and robust construction**.

- The **sector gear** (which converts steering wheel rotation into Pitman arm movement) was designed for smooth operation, reducing wear over time.

- The **Pitman arm** and **steering shaft** were made from **strong, heat-treated steel**, making them resistant to bending or fatigue.

3. **Easier Restoration for Classic Cars**

- Many **1939-1940 Chevrolets** (especially Co-E models) suffer from **steering component failure** due to age, rust, or improper modifications.

- Replacing the entire sector assembly (rather than individual worn parts) **eliminates guesswork** and ensures a **like-new steering system**.

- Some modern replacements may not fit as precisely, leading to **play or misalignment**, which NOS parts avoid.

4. **Increased Vehicle Value**

- If you own a **restored or well-preserved 1939-1940 Chevrolet**, having **original or NOS steering components** can **significantly boost its value** in the classic car market.

- Collectors and enthusiasts **prefer cars with original or period-correct parts**, making NOS components a desirable upgrade.

5. **Reduced Risk of Modern Compatibility Issues**

- Aftermarket replacements may require **adjustments, spacers, or modifications** to fit properly.

- NOS parts are **guaranteed to fit** without modification, reducing the risk of **steering bind, excessive play, or premature wear**.

6. **Historical and Nostalgia Value**

- For collectors and purists, owning **original or NOS parts** adds a **sentimental and historical value** that mass-produced replicas cannot match.

- Some enthusiasts see these parts as **artifacts of automotive history**, making them a **collectible item** in their own right.

7. **Potential for Resale or Trade-In**

- If you no longer need the part, **NOS sector assemblies** can sometimes be **traded in or sold** to other restorers, potentially offsetting some of the cost.

---

### **Cons**

1. **High Cost Compared to Modern Replacements**

- NOS parts are **expensive**, often **2-3 times the price** of aftermarket or reproduction components.

- A **complete sector assembly (steering shaft, Pitman arm, sector gear)** can cost **$500 $1,500 **, depending on condition and rarity.

- This makes them **impractical for budget restorations** or casual drivers who prioritize functionality over historical accuracy.

2. **Limited Availability and Long Lead Times**

- NOS parts are **not mass-produced** and rely on **private collections, auctions, or specialty suppliers**.

- Finding a **complete, matching set** can be **difficult and time-consuming**, sometimes requiring **months of searching**.

- Some sellers may **overcharge** due to scarcity, leading to **price gouging** in the NOS market.

3. **Risk of Counterfeit or Misrepresented Parts**

- The NOS market has **fraud risks**, where sellers may claim a part is **original** when it is actually a **reproduction, modified, or mismatched** component.

- Always **verify provenance** (original packaging, serial numbers, or seller reputation) before purchasing.

- Some "NOS" parts may have been **rebuilt or reconditioned**, which could affect performance.

4. **Potential for Wear or Damage Despite Age**

- Even NOS parts can be **deteriorated** if stored improperly (e.g., rust, bent shafts, worn gears).

- Before installation, you may need to **clean, lubricate, or replace** other components (e.g., **tie rod ends, drag link, or steering column**) to ensure smooth operation.

- Some parts may have **minor imperfections** (e.g., slight pitting on gears) that could affect longevity.

5. **Installation May Require Specialized Knowledge**

- While NOS parts fit easily, **proper alignment and adjustment** are crucial to avoid **steering play, binding, or premature wear**.

- If you re not experienced with **steering geometry**, you may need a **mechanic familiar with classic Chevrolets** to install them correctly.

- Some restorers report that **modern steering columns or linkages** may not align perfectly with NOS parts, requiring **custom fabrication**.

6. **Not Always Necessary for Functional Cars**

- If your **1939-1940 Chevrolet is a daily driver or a project car**, modern **replacement steering kits** (e.g., from **Steering Components, Moroso, or ECS**) may be **just as reliable** at a fraction of the cost.

- Unless you re **restoring for concours or collecting**, the **extra cost may not be justified**.

7. **Storage and Handling Challenges**

- NOS parts are **delicate** and may require **special care** to prevent damage during shipping or handling.

- Some sellers charge **extra for careful packaging**, adding to the cost.

- If the part is **not installed immediately**, it may need **proper storage** (e.g., in a dry, rust-proof container) to prevent degradation.
