I found a nice CHT gauge on eBay that I would mount instead of the ashtray. I know this one says EGT but the seller has one calibrated for the lower CHT range as well but the listing just ended.
I'm away this week so I need your help with the ashtray measurement.
Thanks

BTW, I got a CHT K-Type sensor from him (14mm) with 3m extension and it works well.

If this interests you, I can get the manufacturer....

That's my other option but I'm not sure I like how it obscures the server light and the heater levers.

BTW, is that a dash cap?

Mount it upside down & it doesn't obscure them. Just a thought.

Don't think so but not sure. It does have some cracks in it so it's probably the factory dash It's in a car that is used on the track; hesitate to call it a "track car" as I have only been to one motorsports park but have driven 2 tracks at the park. I drive it to the track; don't have a trailer. I don't worry about the levers as I only have heat on the drivers side; the passengers side heat duct along the side contains oil cooler lines so can't have heat that side.
