Does anyone know how to get a fuel gauge from an Eunos 30x?

As i have got a spare car for parts and wanna get the fuel gauge out of that car to put on the one i'm driving,

because the fuel gauge on the one i'm driving also stays on half way, the empty light still works when its out of fuel.

Does anyone know of any mechanics? so i can get them to get it out for me and put it on the car that i'm driving.

Cheers

year?

its a 1992 model.
