CHT sender 1978 M20J

[wrench]

Anyone have advice on where a good used or new CHT sending unit might be attained? The threaded post for the terminal end is loose on mine. A&P mechanic tells me very hard to find, just hope it doesn't fail or a big instrumentation change will be in the works.

Are you referring to the bayonet style thermocouple?

Thanks for the tip Jim I'll call Dan at LASAR tomorrow.
