Autometer Temperature Gauge with Classic Instruments SN12MM Sending Unit??

[72Z/28]

My temperature sending unit was initially installed on the upper radiator hose. However, I wanted a cleaner look, and ordered the classic instruments sending Unit SN12MM to fit on the passenger side head.

Now I am replacing my old classic instruments gauges with autometer gauges kit.

Automer temperature gauge comes with sending unit.

Just wondering can I use the autometer gauge with my existing classic instruments temperature sending unit or I have to use the autometer sending unit instead.

Will appreciate your input guys.
