No, but I found one of those hand held laser level things really useful....used angle iron to brace against the rims but found I did'nt need it...just resting the instrument on the hubs gives same result.
Parked in a straight line in a long back alley at night, car park or whatever, the laser light shows where the wheels really point over a long distance.
It highlighted what I need to do to stop the scrub...undoing the track rod is another story though.
Something to bear in mind and check though is the equality of ride hieght at each wheel. Measure each from the hub to arch...if its sunk at the front one side it can be adjusted via the torsion bar.....
