Mazda Miata: Roll Bar and Tow Bar

Hi Guys,

I am looking to get a roll bar and a Tow bar fitted to my 98 model Mazda MX5
(Miata) and was wondering if anyone has done this to their car before. I
notice that the owners manual does not recommend fitting a tow bar to this
car.

Does anyone know a place in Sydney Australia where i can get these fitted?
Ta,
