Mark,
Eagle Tree uses what I call a "wrap" thermocouple. It wraps around the cylinder, although it can be tricked into attaching under a bolt and washer. If the cart people have a basic two wire thermocouple adapted to fit under a plug I want some!!!! The downside of the Eagle Tree Thremocouple is that it typically has the resistance sensor at the front of the cylinder, which is not the hottest point on the engine regardless of placement height. The stuff used at work is a bit more sophisticated[)]
Pat,
A quick google of "spark plug thermocouple" netted these:

http://www.challengerwest.com/stratomaster.htm (scroll down a bit, they look to have ones for multiple sizes of plugs under SENDERS)
http://www.performancetrends.com/Dat...TMTempPicture3 (scroll down 5-6 items and they show a K thermocouple for 14mm plugs)
Lots of stuff out there to look at based on this.
