wheel spacers

[loventactical]

I recently installed a 3/2 leveling kit on my 2006 4runner Limited. I have factory 18" wheels and have purchased Nitto Trail Grappler M/t 285/65/18. Rear fit just fine, front won't fit due to hitting the control arm (tires too wide).

Anyone know what size wheel spacers are needed? Also if any other modification will be necessary for this? Any help would be much appreciated.
