[Standard] Connectors for C5718DA Microphone

[Doug Shields]

Hello all,
     I just acquired a very nice Standard C5718DA transceiver.  I would like
to mount the radio beneath the driver's seat in my car.  I would like to
extend the microphone cable about 24" just to be sure it clears everything.
I figure that finding an original extension cable would be very difficult.
Does anyone know where I might find the connectors that are used on the mic
cord?  Any leads on the connectors (or a Standard extension cable) would be
greatly appreciated.  Thanks very much.
