Kind of, you might slightly disturb the centre position of the steering wheel, but the actual geo in terms of toe values etc will still be the same as you arent changing the distance between the two rod ends. If the wheel ends up off centre you can adjust that yourself so long as you add from one exactly what you take from the other (ie turn both 2 flats or whatever) and it will still be sound.
Cheers Chip ...have to see what pans out when I get my head in there.
