That's caused by "bump steer" which is from excessive toe change when the suspension extends/compresses. You can replace the outer tie rods with ones with a longer stud. Some are adjustable for stud length (with spacers) to get the least toe change for your specific vehicle. Also, steering arms are available for some vehicles with a lower tie rod attachment point. Google "bum steer kit for 67 GTO" .....
