Audio jacks

The center to center distance of the audio plugs on the the Yaesu is only 0.3".  So narrow audio jacks must be selected.  Through hole is preferred.  These connectors are likely to be more sturdy and narrower than their SMD counterparts.

Audio cable assemblies

You should be very carefully about what cable assemblies you buy for this.  The connectors on the Yaesu are very close to each other, you'll never be able to plug in two standard cables.
