Only the rear hubs can be spaced, but some wheel spacers on the front will do the trick

You'll also need some extended studs for this type.
However, it is an absolute pig of a job to fit extended studs to the front hubs as they need fully dismantling on a bearing press. A bolt on spacer would be a heap easier, but more expensive.
