Where can you get 1-1,1/2" wheel spacers from in NZ, probably going to change from my Mudzilla 31x11.5 to 31x10.5 but want to keep my wide footprint ( wide footprint = suzuki not tipping over

)also how much would it be to get the wheel centres moved in an inch or two,anybody know?.Truck is road legal.Yeah i know wheel spacers arn't road legal but i can live with that.
