You said that the front end has been rebuilt? Do you know if the front cross member was reset as well? A good way to see if it has is to look at the upper fulcrum pins if the back end nut is real close or up against the fender well it has not been repaired and will have to be pulled, over the years a Tigers front member will sag inward and down and back this will cause the tire rub along with other issues. 8)
