add shims to the top wishbone (pivot end). they'll bolt between the pivot thingy and the chassis and will push the wishbone out to correct the camber. if the pivot is inboard of the chassis mounting point take out some shims (same for each bolt or you'll alter caster too). if this still doesn't work just shorten or extend the wishbone (it's only metal after all). that's some options for you to look at mate.
