OK. The sensor is included in the kit according to AEM website. I have found a vendor that will do them for $320 each if I can get 10 people to sign up. This price includes shipping but to only 1 location. They would have to be shipped to me and I would inturn ship them to you. Let me know.

I may be able to convince Doug and Chris (maybe others too). That is a terrific price!

I am assuming that AEM designed and manufactured the kit in house but, I cannot say for sure. The gauge size is 2 1/16" diameter. Here is the info from their site:
AEM’s Wideband UEGO Controller is also available in a gauge that includes a single-channel analog output with a Bosch O2 sensor in one unit!
AEM’s Gauge-Type Wideband UEGO Controller features an LED readout and sweeping LED “needle” that changes colors as AFR changes from rich to lean. The unit’s 52mm (2-1/16”) gauge housing fits in most gauge pods and can be remotely mounted virtually anywhere.
Key Features:
∙ 24 Color-coded LED display lights provide immediate reference to engine’s air/fuel ratio (AFR) or Lambda
∙ Integrated three-digit display reveals AFR or Lambda in real time
∙ User-programmable 0-5v analog output included for use with data loggers and ANY engine management system
∙ Ideal AFR monitoring tool for carbureted applications and engine dynamometers
∙ Does not oscillate AFR like narrow band sensors
∙ Serial data stream included for output of AFR (RS 232)
∙ Accurate to 0.1 AFR
∙ Bosch sensor included

In a V engine, wouldn't 2 sensors be needed? If only one, where do you mount it? You've got an exhaust manifold coming out of each side of the engine, so wouldn't you want a sensor on each side? Wouldn't that mean you'd have to have two of these gauges, too? 
I also noticed that the Horsepowerfreaks site (linked up above) sells AEM wideband O2 sensor kits seperately. They specifically have single channel and dual channel kits, the latter being for V style engines. Will we need to get an extra sensor for the Z, and if so, will the gauge even support a dual channel setup?
Using only one sensor on one side of the engine, it would seem that you'd only be measuring the AFR from one bank of cylinders. That would work as long as you don't get a problem in a cylinder on the *other* side.

jreiter, you're correct.
There is only one sensor and the gauge can only support one sensor. The engine should be running balanced A/F ratios between the two different sides, so it should be fine if you just monitor one side.
If you wanna get real technical, you should have six Wideband sensors and six gauges, one for each cylinder, but that's getting a little ridiculous. Just tune conservatively to make up for any airflow differences between the three cylinders on the same bank and there's no problem just monitoring one bank.

was it cylinder 1 or 6 that tends to be running somewhat more lean then the rest?
i'd just put it on that side and call it a day. this way i get a worst case scenario a/f.
