I don’t think it matters where it is made. We shouldn’t confuse the quality of parts with compatibility of parts.
For example: If you buy a PerTronix ignition, use the coil that they suggest. Use the ballast they suggest. If they don't specify a ballast, don’t use one.
The biggest problem seems to be mixing parts. If you buy a PerTronix ignition & Accel coil, then who knows what you got unless you understand how to figure it out.
Aftermarket and oem ignitions are designed as a complete system. The parts work together. Try plugging your tv into a 220v outlet & see how that works out for you. Those two thing are not designed to work together.
