Unfortunately, Moog and others don't treat classic cars as a viable customer base anymore. So many cranks and rods are made in China now. I would trust Taiwan over Chinese nowadays.
It’s not even China that’s really the problem. The company contracting the factories sets the standard for quality control, they can inspect parts and follow up on issues just like anywhere. But that costs money. The problem in this case is Moog, clearly they don’t give a crap if the products they’re making meet any kind of real standards. If they did they would have a quality control system that would find the substandard parts being made and remedy the issue.
Instead, we as customers are buying parts that don’t fit and won’t last.
