tires hitting after front end rebuild

I did a disc brake conversion and rebuilt the front suspension. (new ball joints, bushing etc,) Now my front wheels hit my front fender when I turn. I haven't had the front end alined yet but i turned the cam bolts as far as I could to pull the wheel away from the fender and it still hits. These tires were on the car before and worked. I have to run a spacer behind the front wheels now to keep them from rubbing the calipers but I don't know why that would make a difference. My tire are 26" diameter. shouldn't they fit?
