The pictures I've seen look just like Chick's. Whether they are an accurate portrayal is another matter.
I just picked up a 6428845 in the GM Box on Ebay (Item 232407826527) and it still says Made in USA with the square wire end and not the circular wire end. I believe they have been discontinued from GM some time now. If still available from GM it must be a GM Restoration Part, hence why it says Made in China.
