Need Top Pivot Pins

I need two pins to replace the one shown in the photos, please. There is no identifying information on either the bi-fold metal mirrored closet door, or these pins.

Approximate dimensions from the drawing are:
Metal threaded pin: A) 1.15" B) .183" C) .183" D) .825" E) .262" F) .230"

Plastic cap: G) .751" H) .150" I) .094" J) .751" K) ID .269", OD .340"
L) OD .495" M) ID .251" OD .396"

Spring: N) .589" O) .474" Wire diameter=.029"

Thanks for your help.

If the entire 3 piece assembly isn't available, I could make do with just the white plastic caps.
