Yes there are some parts still made in America... The ones I know of are not things you would likely deal with but they are things I might some day use if I ever trade in this bucket of bolts an a new Sticks and Bricks.
There is a company, I think in Mississippi that still winds it's own coils and several other parts. They could not find a supplier that met their quality standards.. I know of a few other parts made that way.. Actually own 2 such parts (Microphone connectors) and have E-mailed the guy responsible.
