Ignition Coil Guide for the 1967-1968 Glas 3000 GT V8
Keep your rare classic Glas V8 running strong with a reliable new aftermarket ignition coil.
- A failing ignition coil on your Glas 3000 GT can cause critical issues like stalling or a no-start condition.
- Original OEM parts are virtually nonexistent; modern aftermarket brands like Standard Ignition and Spectra are the primary options.
- Replacement is a simple, DIY-friendly task that can be completed in under 30 minutes with basic tools.
- Standard Ignition (SMP) is generally regarded as a higher-quality choice for reliability compared to more budget-oriented brands.
Understanding the Ignition Coil in Your Classic Glas
The 1967-1968 Glas 3000 GT, with its unique SOHC V8 engine, uses a traditional, single canister-style ignition system common for its era. This system is straightforward: one coil provides the spark for all eight cylinders. Over time, the constant heat and vibration from the engine can cause the coil's internal windings to break down, leading to poor engine performance or a no-start condition. Given the rarity of the Glas 3000 GT, finding a direct replacement can seem daunting, but modern aftermarket parts are available that meet the original specifications.
Symptoms of a Failing Ignition Coil
A weak or failed ignition coil can cause problems that are hard to ignore. If you experience any of these symptoms, your coil may be the culprit:
- Engine Misfires: The engine may sputter, shake, or run poorly, especially under acceleration. This happens when a cylinder fails to fire correctly due to a weak spark.
- Hard Starting or No Start: The engine may crank but refuse to start, or take much longer than usual to fire up. This indicates the spark plugs aren't getting the high voltage they need.
- Sudden Stalling: The vehicle may stall unexpectedly while driving or when idling. This can be dangerous and points to an intermittent failure within the coil.
- Reduced Power and Poor Fuel Economy: A weak spark leads to incomplete fuel combustion, resulting in less power and more trips to the gas station.
No Specific Recalls or Bulletins Found
Due to the extreme rarity of the Glas 3000 GT, no vehicle-specific recalls or Technical Service Bulletins (TSBs) from the NHTSA regarding the ignition coil were found during research. The issues listed are common to ignition systems of this vintage.
Choosing the Right Aftermarket Ignition Coil
Finding an original "Glas" branded ignition coil from the 1960s is nearly impossible. Fortunately, the aftermarket provides reliable, modern replacements. The key is to choose a quality part that is compatible with your V8's classic points-style ignition system.
Brand Options: Spectra vs. Standard Ignition
Two common brands you will find are Spectra and Standard Ignition (often sold as SMP).
- Standard Ignition (SMP): Often considered a professional-grade aftermarket brand, Standard Motor Products has a long history 🎬 Watch an overview of Standard and Blue Streak ignition coils. of producing reliable ignition components. Many technicians trust them to engineer parts that identify and improve upon the weak points of original designs. For a rare classic like the Glas, a brand with a reputation for quality engineering is a strong choice.
- Spectra: Spectra offers a more budget-friendly option. While some users report success with their parts, others have experienced premature failures, suggesting quality can be inconsistent. For a daily driver or a simple repair, it can be a viable choice, but for a specialty vehicle, the reliability of a higher-tier brand may be worth the small price difference.

Frequently Asked Questions
Is a modern aftermarket coil better than the original?
Yes. Ignition coil technology has improved significantly since the 1960s. A new aftermarket coil from a quality brand will likely be more reliable and provide a more consistent spark than a 50-year-old original part.
Can I replace the ignition coil myself?
Yes, this is a very DIY-friendly job for someone with basic tools and mechanical knowledge. The coil is typically held on by a simple bracket with two small bolts and has a few easy-to-access electrical connections. The entire job can usually be done in under 30 minutes.
How do I know the coil is the problem, not the spark plugs or distributor?
A simple test is to check for spark. You can carefully remove the main wire from the distributor cap, hold it near a metal part of the engine, and have someone crank the engine. A strong, blue spark indicates the coil is likely working; a weak, yellow spark or no spark points to a bad coil. However, for a definitive diagnosis, it's best to consult a mechanic or use a multimeter to test the coil's resistance.
Are there any common mistakes when ordering this part?
The most common mistake is not ensuring compatibility. While many canister coils look similar, they can have different internal resistance. Make sure the part you order is specified for a 1967-1968 Glas 3000 GT or a compatible vehicle with a V8 and a points-style ignition system.
