Using a 12Volt temperature sending unit on a 6 volt system

[johndickred]

I need some help. I purchased a 55 t bird. The temp gauge did not work. My mechanic determined that the gauge was working so I ordered a new sending unit. When we went to replace it we discovered that my 55 has 57 heads and a 57 12 volt sending unit. The hole opening does not accomidate the larger sized 55 sending unit I bought. Is there a way to use the 57 12 volt sending unit with a resistor or something to work in my 6 volt system and gauge?
