Ignition Contact Set Replacement Guide for the 1936 GMC T14
Keep your classic GMC running strong with a reliable ignition contact set.
- For a 1936 GMC T14, a new aftermarket ignition contact set is the only viable option, as OEM parts are no longer made.
- Symptoms of failure include hard starting, rough running, stalling, and poor acceleration.
- Always replace the ignition condenser at the same time as the points to prevent premature failure of the new parts.
- Standard Ignition is a readily available brand, with its 'Blue Streak' line being a recommended premium option for classic vehicles.
Understanding the Ignition Contact Set in Your Vintage GMC
The ignition contact set, or points, is a key part of your 1936 GMC T14's ignition system. Unlike modern cars with computers, your truck uses this simple mechanical switch to time the engine's spark. The set consists of two contacts that are pushed open by a cam on the distributor shaft as it spins. Over many miles, the small rubbing block that rides on the cam wears down, and the electrical contacts can become burned or pitted. This wear and tear is normal, and the points are considered a regular maintenance item that needs periodic replacement.
Symptoms of a Failing Ignition Contact Set
When the points in your T14 begin to fail, you will notice a clear drop in engine performance. The signs are often subtle at first but will worsen over time, and could eventually leave you stranded. Watch for these common symptoms.
- Hard Starting: The engine cranks but struggles to fire up or won't start at all. This can happen because worn or dirty points can't deliver a strong, consistent spark.
- Engine Misfires and Rough Running: You may feel a shake or shudder from the engine, either at idle or while accelerating. This is caused by an inconsistent spark failing to ignite the fuel in each cylinder properly.
- Stalling: The engine may die unexpectedly, especially at low speeds or when you come to a stop. This is a safety hazard, as it can happen in traffic.
- Reduced Power: The truck may feel sluggish and hesitate when you press the gas pedal. Inefficient combustion from a weak spark means the engine isn't producing its full power.
No Recalls or TSBs Found
As of early 2026, no specific recalls or Technical Service Bulletins (TSBs) from GMC or the NHTSA exist for the ignition system on the 1936 GMC T14. This is normal for a vehicle of this era, as these issues are addressed through routine maintenance.
Choosing the Right Aftermarket Ignition Contact Set
For a vintage vehicle like the 1936 T14, new Original Equipment Manufacturer (OEM) parts are no longer produced. Your only option is a new aftermarket part. Fortunately, established companies still manufacture these components.
Available Brand: Standard Ignition
Standard Ignition (also known as Standard Motor Products or SMP) is a well-known aftermarket manufacturer that produces parts for classic vehicles. They offer a direct replacement ignition contact set for the 1936 GMC T14. For classic car applications, their premium "Blue Streak" line is often recommended by enthusiasts for its quality and reliability. Given that the points are a critical and inexpensive part, choosing a quality replacement is a smart investment in your truck's reliability.
Pro Tip: Replace the Condenser and Check the Distributor
It is highly recommended to replace the ignition condenser whenever you replace the points. The condenser absorbs voltage to prevent the points from arcing and burning out. A bad condenser will cause a new set of points to fail quickly. Also, check for side-to-side play in the distributor shaft. A worn distributor bushing can make it difficult to set the point gap correctly, leading to a rough-running engine even with new parts.

Frequently Asked Questions (FAQ)
Can I still drive with a failing ignition contact set?
You can for a short time, but it's not recommended. Symptoms like stalling and misfiring will only get worse, and you risk being stranded when the points fail completely.
How often should ignition points be replaced?
On a classic vehicle, points are a routine maintenance item. Service intervals can range from 5,000 to 15,000 miles, depending on use. For a truck that is driven infrequently, it's good practice to inspect them annually.
Is replacing the ignition contact set a DIY job?
Yes, for those with mechanical experience. The process is straightforward and requires basic hand tools and a feeler gauge to set the point gap. However, if you are not comfortable working on a distributor, a professional mechanic familiar with classic cars can do the job quickly.
What is the difference between standard and "Blue Streak" points?
"Blue Streak" is a premium line from Standard Ignition, often made with higher-quality materials for better durability and performance. For a classic vehicle where reliability is key, the premium option is often worth the small extra cost.
