The **Oerlikon (Oer) IN2470S 1970 1972 Buick Skylark GS 455 Rally Gauge Pack with Flat Lens** is a meticulously crafted, high-performance aftermarket instrument cluster designed to transform the stock gauges of your classic Buick Skylark GS 455 into a sleek, functional, and eye-catching rally-inspired dashboard. This gauge pack is a direct nod to the legendary **1970 1972 Buick GS 455 Rally** models, which were engineered for both luxury and high-speed performance, and it captures the spirit of those iconic cars with precision-engineered dials and a bold, retro-modern aesthetic. The **flat lens** design ensures a clean, unobstructed view of the gauges, eliminating the glare and distortion often found in traditional curved lenses, while the **IN2470S** series is renowned for its durability, accuracy, and seamless integration with the original wiring harness, making it an ideal upgrade for enthusiasts who demand both authenticity and modern reliability.

At the heart of this gauge pack lies a **triple-dial layout**, featuring a **speedometer** with a sleek, white or black face (depending on the model variant) and a **tachometer** that extends up to **7,000 RPM**, catering to the high-revving demands of modern performance engines while maintaining the classic Buick styling cues. The **fuel gauge** is positioned centrally, offering a clear, uncluttered readout, while the **oil pressure gauge** and **water temperature gauge** (if included in the pack) provide essential performance monitoring without sacrificing the rally-inspired flair. The **flat lens** is crafted from high-quality, scratch-resistant polycarbonate, ensuring long-term clarity and resistance to yellowing, while its matte or glossy finish can be tailored to match your car s interior whether you prefer a subtle, understated look or a bold, high-contrast display.

One of the standout features of this gauge pack is its **Oerlikon engineering**, which guarantees **OEM-level accuracy and reliability**. The gauges are calibrated to match the original Buick specifications, ensuring that your speedometer remains precise at highway speeds while the tachometer provides real-time feedback for tuning and performance driving. The **rally-inspired design** includes **white or black dials with bold, high-contrast markings**, often featuring **red or black needle pointers** for enhanced visibility, and the **backlit options** (available in some configurations) allow for easy reading in low-light conditions, making it ideal for night driving or track sessions. The **seamless integration** with the original wiring harness means no modifications are required to the factory harness, simplifying installation and ensuring a clean, factory-like appearance.

Beyond its functional and aesthetic appeal, the **Oer IN2470S gauge pack** is built to last, with **gasketed seals** preventing moisture ingress and **durable mounting brackets** that secure the gauges firmly in place. The **flat lens design** not only reduces glare but also allows for a more modern, minimalist look, making it a favorite among restomodders who want to blend vintage charm with contemporary performance enhancements. Whether you re driving your Skylark GS 455 on the street, the track, or a weekend cruise, this gauge pack elevates the driving experience by providing **instant, at-a-glance feedback** while paying homage to the car s legendary rally heritage. Perfect for both **restoration projects** and **high-performance builds**, the **Oer IN2470S** is a must-have for any Buick enthusiast seeking a perfect fusion of heritage, precision, and style.

### **Pros and Cons of Buying a 1970-72 Buick Skylark GS 455 Rally Gauge Pack with Flat Lens**

#### **Pros**

1. **Classic American Muscle Car Appeal** The 1970-72 Buick Skylark GS 455 is a highly sought-after muscle car from the transitional era between big-block power and early emissions restrictions. Its aggressive styling, including the Rally Gauge Pack and flat lens headlights, makes it a visually striking car, especially in showroom condition.

2. **Strong Engine Option** The 455 cubic inch V8 (available in 1970-72) was one of Buick s most powerful engines of the era, producing around **300-350 horsepower** in stock form. While not as legendary as a 426 Hemi or 450 Magnum, it remains a solid muscle car engine with good reliability if maintained properly.

3. **Rally Gauge Pack (RGP) Enhances Driving Experience** The Rally Gauge Pack includes a tachometer, oil pressure gauge, and water temperature gauge, which were rare in passenger cars at the time. These gauges provide better feedback for driving, making the car more engaging for enthusiasts.

4. **Flat Lens Headlights** The flat lens headlights (introduced in 1970) were a stylish upgrade over the previous curved lenses and are highly desirable among collectors. They add to the car s vintage appeal and make it stand out compared to later models with rectangular headlights.

5. **Potential for Restoration or Modification** These cars are often found in varying conditions, from rusted-out shells to well-preserved examples. A project car could be restored to concours condition, or the engine could be upgraded (e.g., turbocharging, fuel injection, or a modern engine swap) for improved performance.

6. **Niche Market with Good Investment Potential** While not as valuable as a 1969-70 Skylark GS 400 or a 1967-69 Riviera, the 455 model has a dedicated following. Properly restored examples can appreciate in value, especially if kept in original condition or with high-quality restorations.

7. **Comfortable Ride for Its Era** Buicks of this era were known for their smooth ride and quiet cabin, making them more comfortable than many of their GM rivals. The Skylark GS 455 retains this reputation, offering a balance of performance and comfort.

8. **Availability of Parts and Support** As a Buick, parts are still relatively accessible, though some rare components (like original Rally Gauge Pack gauges) may require sourcing from specialty suppliers or restoration shops. Buick clubs and forums (e.g., Buick Skylark Club of America) provide community support for owners.

#### **Cons**

1. **High Maintenance and Restoration Costs** Many 1970-72 Skylark GS 455s are in poor condition, with rust, worn suspension, and outdated electrical systems. Restoring one to original or better condition can be expensive, especially if the frame or body is severely corroded.

2. **Emissions and Modern Compliance Issues** These cars were built before modern emissions standards, meaning they may not pass smog checks in some states without modifications (e.g., installing an OBD-II port, upgrading the exhaust system, or switching to a modern engine). Some states require **California Smog Check** compliance, which can be difficult for pre-1975 vehicles.

3. **Reliability Concerns with Age** The 455 V8, while powerful, is prone to issues like **head gasket failure, oil leaks, and rod bearing wear** if not properly maintained. The transmission (especially the Turbo-Hydramatic 400) can also be finicky, requiring frequent fluid changes and potential rebuilds.

4. **Fuel Economy and Modern Driving Habits** With a large V8, fuel efficiency will be poor by today s standards (around **10-12 MPG combined**). Running the car daily on premium fuel will add to ownership costs.

5. **Insurance Costs** Classic muscle cars like this are expensive to insure, especially if they are restored or modified. Rates can be **3-5 times higher** than a modern sedan, depending on the insurer and coverage level.

6. **Limited Practicality** The Skylark GS 455 is a **two-door coupe**, meaning it has limited rear seating and cargo space. It s not ideal for daily use with a family or for hauling equipment.

7. **Depreciation Risk** While some classics appreciate, others depreciate quickly if not maintained. If the car is not restored or driven occasionally, its value may stagnate or decline.

8. **Driving Challenges** The car s weight (around **4,000 lbs**) and older suspension setup make it less nimble than modern cars. Handling can be stiff, and braking performance may require upgrades (e.g., larger drums or discs) for safe stopping power.

9. **Finding a Good Example Can Be Difficult** Many 1970-72 Skylark GS 455s are either **rusted out, poorly restored, or stripped for parts**. Locating one in **original condition with a clean title** can be challenging and may require extensive searching.

10. **Resale Value Depends on Condition** Unlike a well-preserved 1969 Skylark GS 400, a 455 in average condition may not hold value. Buyers typically expect **concours-level restorations** or at least a **driven-but-well-maintained** example to justify premium pricing.

### **Ending Conclusion**

Buying a **1970-72 Buick Skylark GS 455 Rally Gauge Pack with flat lens headlights** is a **high-risk, high-reward** decision. It is best suited for **enthusiasts who appreciate classic American muscle cars, have mechanical skills, and are willing to invest significant time and money into restoration or maintenance**.

If you are looking for a **daily driver**, this car is **not practical** due to its poor fuel economy, high insurance costs, and limited modern comforts. However, if you are a **restoration project enthusiast, a collector, or someone who enjoys driving a piece of automotive history**, it can be an incredibly rewarding purchase.

The **Rally Gauge Pack and flat lens headlights** make this model stand out, but they also come with **higher maintenance demands** than a simpler classic car. **Budget for at least $10,000-$20,000 ** for a **restorable example**, and be prepared for **ongoing costs** for parts, labor, and potential modifications to meet modern standards.

---

### **Final Recommendation**

- You have **mechanical experience** or access to a trusted mechanic.

- You are **committed to restoring or maintaining** the car properly.

- You **prioritize driving experience and classic styling** over modern convenience.

- You are **willing to invest in a long-term project** rather than a quick flip.

- You find a **well-documented, clean-title example** (preferably with original Rally Gauge Pack and flat lenses).

- You need a **daily driver** with low running costs.

- You are **unprepared for high insurance, fuel, and maintenance expenses**.

- You cannot **source parts reliably** or lack the skills to work on a vintage Buick.

- You expect **quick appreciation in value** this is a **collector s item**, not a short-term investment.

- **Inspect thoroughly** (or have a professional inspect) for rust, engine condition, and transmission health.

- **Test drive** to ensure the car runs smoothly and handles well.

- **Budget for restoration** (or plan to modify it for modern use).

- **Join Buick enthusiast forums** for advice on parts and maintenance.

For the right buyer, this Skylark GS 455 can be an **incredible addition to a classic car collection** but it demands **respect, patience, and financial commitment**.
