WTB - Tuff Steering Wheel

Hi All,
Want to get a correct looking Tuff Steering Wheel for my 71 Dodge Demon. Do I need anything else, i.e. boss kit, horn button.
Doesn't have to be an original one. As long as the repo one are as good, that will do.
As I live in Australia I want to get it right first time.
Any help appreciated.
Cheers,
Glenn.
