If on the front suspension that you have, the upper a-arm mounts inboard of the frame mount you can install longer upper inner a-arm bolts and move the upper control arm in 1/2 to 3/4". Then, if you can weld or know someone who can, cut and narrow the lower control arm the same 1/2" to 3/4" (this is a good time to replace the lower ball joints).
If the upper control arm is outboard of the frame mount, you will have to cut and shorten that one as well.
You may have to trim the inner and outer tie rod ends a bit to make up for the narrowing to set the toe, but there may be enough adjustment without having to do that.
Doing this will alter the suspension geometry but narrowing only a small amount won't cause any issues with normal driving and is a cheap way to improve or eliminate a clearance issue with the outer fender lip.
