Having said that, you can get the HEADPHONE side plug at The Shack, but
the mic
plug is an old telephone switchboard style 0.206" diameter dinosaur that
is ONLY
used these days for aviation. Pricey.

Every aircraft owner I know has a beat-up old pair of non-functional (or
barely functional) headphones in a box in the hangar somewhere.

I'll bet you could buy one of them for a song (or, better yet, get it for
free), cut the plugs off, and have your part.
