I want to change my Behringer Fuzz UZ 400 to get a more vintage tone.
It use a silicon transistor K184/GR7C.
Which germanium transistor can I put in it? Or not?

Information
You can't just change the transistors. All the resistors would need to be changed too, since silicon biases completely differently to germanium. You can improve the tone of a silicon fuzz face by adding low value base to collector capacitors at each transistor. Start with (say) 100p and try increasing each one until you get the tone you want. In most situations, especially a band situation, a modified silicon FF is indistinguishable from a germanium one - except that the output will be louder.
