Jack it up and remove both front tires and set it down so the weight is on the axle and have a friend help you check out exactly how much toe in or toe out you have by using two steel carpenter squares and a tape measure by laying the squares up against the brake drum or rotors on both sides so there flush up against where the wheel is and measure out the front side around 15 inches from the spindle center and then about the same amount out the other way and see how much difference there is
That is how I found a bent rear end housing on one of my old street and strip cars, that rascal was 5/8 closer on the front side than the back side
Please let us know what you find
