EGT Replacement Probes for the 914

What kind of cockpit instrumentation do you have? The manufactures of this equipment usually sell replacement probes and sensors matched to your equipment making replacement the easiest/quickest. 

I'm wondering the same thing. I've got a Dynon D180 and 2 egt probes on my 914. One has been reading too low to be correct (reads 4-500° while the other is at 14-1500°) as the engine runs perfectly. I'm planning on swapping the probes to confirm the fault but I'd like to have a new (preferably inexpensive) probe to swap it with. Any recommendations?
