These plugs are not standard sizes, and your local electroncs store will
not
have them...Numerous suppliers handle both mic and head set plugs... Try
Gulf Coast Avionics, Eastern Avionics, Aircaft Spruce, etc... A bit of a
google should turn them up...

Pilot headset are broken at both plugs. Can I just
take this in to Radio Shack and expect them to sell me the correct
plugs
so I can cut and reattach? or do I need to be looking for something
special?
