EGT Probe Source?

Time to replace them on my IO-390 powered 7A. Advanced EFIS panels are in the panel (came with the plane) which require the ungrounded type K. Considering the GRT long-life type but can't find where they make the ungrounded type K recommended by AFS. Aircraft Spruce hasn't been much help the far, so appreciate any insight on sourcing these.
 
Found this in the Q&A on ACS for the Alcor probes. You can also order from Dynon (owner of AFS). From their order form: EGT, Hose Clamp, 1.00-2.25”, Lycoming/Continental/Superior$36 P/N: 100405-00

What are the differences between this probe P/N 86255 and P/N 86317?
P/n: 86255 is a grounded probe designed for use with analog indicators, versus p/n: 10-86339 (86317 or 86343) is ungrounded designed to be used with digital indicators.

Thanks for the insight. Called Advanced and they have what I need. Sensor Connection apparently doesn't have the single wire K type EGTs.
