Can't speak for AMD but a lot of it is made overseas. Years ago on another forum a guy supplied AMD with NOS rear quarters for 71/2 RR/Satellite. They made the dies off the NOS sheet metal then after that they started reproducing it. Where the dies where made who knows but after AMD had them all the other places had them also. Since the pandemic a lot of things changed and they may need to have orders for a part before they run a production of them. This was the case with some sheet metal before the pandemic.
