regular water temp gauge for trans temp.

[69Beauty]

Planning on filling the vacant hole in my cluster (vacuum) with another temperature gauge and would like to use a sender in my transmission to monitor that. my problem is that the gauge has a specific resistance (300-55) or somehting like that and the hole in my trans pan is for 1/8 thread so i cant use a cylinder head sender so i wanna know if you know of a sender thats 1/8 and has same resistance as factory water temp. or a sender that is close and i could put an inline resistor to make it work... any help is appreciated.
