That's why its good to pickup NOS or NORS American made parts when you see them.More and more replacement parts are being made offshore and the quality is just not as good in many cases.We have had this discussion before.Dennis Carpenter is a good example.More of his "repro's" are being made offshore because of the labour cost but they are NOT as good quality wise.

  

Bear with my explanation and find a difficult problem.
I bought a '57 Ranchero a few months ago and the temp gauge read comfortably low but the fuel gauge was showing about half what I was putting in the tank. Then my turn signals stopped working at the same time my ignition switch required a bit of push in or pull out while turning to "start".

Did figure the original switch was going bad and ordered up a new Motorcraft. Went to install it and low and behold the existing switch looked nearly brand new BUT WAS FALLING APART. Someone had put in some cheap foreign switch and the manufacturer failed to adequately crimp the four metal tabs. It literally fell apart in my hands.

Motorcraft switch installed. Gauges read properly, turn signals work. They are powered through the ignition switch

Moral of story: Please buy American made stuff, especially electronics, whenever you can
