Stilo rally com's how to adapt on the cheap?

I've already posted this question at special stage, but you guys know everything, so I'm posting here as well.

I'm signed up and excited about co-driving my first stage rally at the Sandblast (www.sandblastrally.com), but have a little detail to iron out yet - how to connect to my driver's intercom? My driver has a Stilo WRC-DES intercom (http://stilo-usa.com/intercoms/wrc-des-intercom) and Stilo helmet to connect to it. I have a road racing full face helmet with no integrated com's. For road racing I've been using a hands free radio headset with a 'Kenwood' style connector that looks like this: for pit com's.

Is there an adapter to go from one to the other, OR, if I need to just buy a Stilo compatible headset, where would I find such a thing? This possibly being needed for just this one event, is there a compatible full face headset I can borrow, rent, or steal from someone on this forum?

Thanks in advance!

PS I might not be opposed to just making an adapter if I knew what the connector coming out of the Stilo was - it's not a standard stereo jack I'm familiar with.

I've reverse engineered the Peltor connections.

Google pooped this out, which mentions that Peltor and Stilo use the same connector.

In the mean time,

The guys here: http://www.pciraceradios.com/ Said they'd custom build me a full face headset with the appropriate female connector for the Stilo intercom for $120. Pricey for a headset, but pretty reasonable for a custom job, IMO, I gave him a credit card number and let him go for it.
