Steering lock difference

[A TR7 16V]

There is a difference between the positive and negative clearance between the right and left wheels and the roll bar as shown in attached pics.

Would this be because the garage that fitted the rack set the track rod ends wrong?

I think they may have been trying to line up the steering shaft so the indicators cancelled, like I insisted they should, without uncoupling the bottom knuckle from the shaft.
