To find the correct point gap:
1. Consult your owner's manual: This is the best source for the precise specification for your specific car. The manual should list the correct point gap setting.
2. Check the distributor: Look for a sticker or marking on the distributor itself. Sometimes the manufacturer's recommended gap is printed directly on the distributor.
3. Consult a Ford parts catalog: A parts catalog specific to a 1967 Mustang 6-cylinder will list the specifications. You'll likely need to identify your engine's specific code to find the most accurate information.
4. Use a reliable online resource: While less precise than the above methods, some reputable online Mustang parts suppliers or forums may provide general guidelines. However, always prioritize information found directly on your vehicle or in its original documentation.
General guideline (Use with caution): While not a guaranteed correct setting for your specific engine, a common point gap for many points-type ignition systems in that era is around 0.016 to 0.018 inches (or 0.4 to 0.46 mm). But again, do not rely on this without verifying it with your car's documentation. Incorrect point gap can lead to poor engine performance and damage.
