Ignition Contact Set Guide for the 1967 Chevrolet K20 Panel
Keep your classic K20 Panel's ignition system reliable by understanding its most important tune-up part.
- The ignition contact set (points) is a normal wear item on your 1967 K20 Panel that requires periodic replacement every 12-15k miles.
- Symptoms of failure include rough running, stalling, hard starting, and poor acceleration.
- Always replace the condenser at the same time as the points to prevent premature failure of the new set.
- Standard Ignition is a reliable aftermarket brand; their premium 'Blue Streak' line offers enhanced durability.
Is Your K20 Panel's Ignition Contact Set Failing?
The ignition contact set in your 1967 Chevrolet K20 Panel is a part that is designed to wear out over time. The rubbing block that rides on the distributor cam wears down, and the electrical contact surfaces pit and burn from the constant arcing. This is normal, but it leads to very noticeable engine problems. Recognizing the signs of a failing set of points can prevent you from being stranded.
Common Failure Symptoms
- Engine Misfires or Runs Rough: Worn or dirty points cause an inconsistent spark, leading to a shaky idle and hesitation during acceleration.
- Hard Starting or No-Start: If the points are too worn or misaligned, they can't trigger the coil correctly, resulting in a weak spark or no spark at all.
- Engine Stalling: The engine may stall at idle or when coming to a stop because the weak spark can't keep the engine running at low RPMs.
- Reduced Power and Poor Fuel Economy: Incorrect point gap affects the coil's charging time (dwell), leading to inefficient combustion and a noticeable loss of power.
Choosing a New Aftermarket Ignition Contact Set
For a classic vehicle like the '67 K20 Panel, new original equipment (OEM) parts from GM are generally no longer produced. The market is well-served by quality aftermarket brands that have been making these components for decades. For this part, aftermarket is the standard and most practical choice.
Standard Ignition (Standard Motor Products) is a widely available and trusted brand for ignition components. They offer different product tiers, which may account for the price range of $21.11 - $37.15:
- Standard Replacement: These are quality, OE-style points designed to meet original specifications. They are an excellent choice for a stock truck used for daily driving or general use.
- Blue Streak Premium Quality: Standard's premium line, often featuring higher-quality materials for the contacts and rubbing block for longer service life and more consistent performance. For the small price difference, a premium set is often a worthwhile investment.
Pro Tip: Always replace the condenser when you replace the ignition contact set. A faulty condenser will cause new points to burn out very quickly. It's an inexpensive part that ensures the longevity of the new contact set.

Frequently Asked Questions (FAQ)
How often should I replace my ignition points?
For a regularly driven truck, inspecting and possibly replacing the points every 12,000 to 15,000 miles is a good practice. If your K20 Panel is a weekend vehicle, a yearly check-up as part of a standard tune-up is recommended.
What's the difference between points and electronic ignition?
Points are a mechanical switch that wears out and needs regular adjustment. Electronic ignition, like an HEI system or a conversion kit, replaces the points and condenser with a maintenance-free magnetic pickup and electronic module that creates a more consistent and hotter spark. While many owners upgrade to electronic systems for reliability, a properly maintained points system works very well.
What tools do I need to replace my ignition points?
You will need basic hand tools like a screwdriver, a feeler gauge to set the initial point gap, and ideally, a dwell meter to accurately fine-tune the adjustment with the engine running. A timing light is also needed to check and adjust the ignition timing after the points have been replaced.
Are there any recalls for the ignition system on my truck?
No, there are no recalls from the NHTSA for the ignition contact set on a 1967 Chevrolet K20 Panel. Major GM ignition recalls in recent years were for much newer vehicles with different system designs and do not apply to your classic truck.
