Help finding part for headset jack

The retainer nut and fiber washer on the passenger headset jack has gone missing... This is the thin nut on the panel that holds the jack onto the rear of the instrument sub panel.

Don't want to buy a whole new jack but I cannot find a part number to order...
Any help would be appreciated.

If you have some laying about I will compensate you for the mailing costs.

Thanks

I got a collection of these

from many years of aircraft restorations. Just tell me if it is the mic or headphone jack. They might be the same but I'm not sure. Just email me your mailing address and forget about a payment. I think I can afford a $.49 postage

I believe spruce sells the shoulder washers and fiber washers individually. If not, Digikey should have them.

Stein sells them.
