This is true. Around 1980 or so, I worked on a 76 Chrysler Cordoba, 318 engine, made a weird noise around the lower front of the engine. Air pump for the smog system noisy. I removed the pump and the bypass valve, that was the culprit. Turning it over, it had GM cast into it. Chrysler was buying smog pump hardware from GM. Makes sense. Why does each manufacturer have to reinvent the same wheel every time? At least those parts then were made in America!
