I know how raising and lower the steering linkage can cause the toe to be off when the car raises up and toe out on turns. His did not seem to change much as it was only a little and it has handled the same to us. I remember my brothers tube frame 68 Cuda had problems when he first ran it using a steering rack as his toe was way off when the car lifted and they had to add spacers on the end of the tie rod ends to correct it. You are right about that for sure. But honestly we only had to change his 1/4" or a tiny bit more but definetly not more then a 1/2". Ron
