More on CHT probe replacement

I've been researching how to replace an old AC Spark Plug CHT probe in our
Aztec. AC doesn't make them anymore and the replacement Rochester brand
probe operates at a different resistance range requiring the gauge to be
removed, shipped out and recalibrated. Not a fun proposition.

Rumor, and a couple parts houses, have told me that the American Bonanza
Society published an article about this problem and a solution is to install
an 82ohm resistor inline with the probe to account for the difference
between the AC and the Rochester gauges. Sounds easy enough.

Is there a group member that belongs to the ABS that could verify the
article and possibly post or email me a copy??

Any other thoughts or comments about this??

Thanks again, again!!
