It's not a new style bayonet type two wire probe. It's an old AC (as in AC
Delco) single wire screw in RTD (resistance type device). It looks like a
little spark plug on the connector end and a short thermocouple on the
cylinder end.

The probe p/n has changed a couple of times, with a different gauge
needed for each probe change. Been awhile since I worked on an older
Aztec, but these guys have been able to come up with what I needed to
get any Piper oil temp/CHT gage up-and-running.

Only issue is, sometimes you need to send them your gage and have them
calibrate it to their probe...
