GRT Avionics

I'm installing your EIS system and replacing my Electronics International probes with GRT probes. The EI probes were 3/16" and the GRT probes are 1/8" so my exhaust pipe holes are now too big. What's the best solution to this?

Thanks

The flange on the GRT Probe is large enough to cover the hole from the othe probes, so you can leave it if you would like to. Other wise the other option is to have the pipes welded and then drill a new hole the right size.
