Wheelbase doesn't match, 25.9" tire hits on front right, 70 duster

I just posted this same question about a week ago about my 67 Dart. I bought a set of 26" front tires also and on my car the right front tire will hit the fender when you turn it. Drivers side is fine. I did some measuring and found that the passenger side tire sits forward 5/8" farther than the drivers side tire. Now it looks like I am not the only one. I have also looked at pictures of other Darts and I can physically see the difference in fender to tire distance on those cars as I can on mine. Also I have completely rebuilt the whole front end on my car.
