adjustable uppers - method

[Scott Atk]

I was wondering if anyone had a method that worked for them to adjust the uppers. I was thinking that if they're not both EXACTLY the same length that they could be binding and you would never know. So how is everyone adjusting theirs on the car to ensure equal lengths?
Thanks,

If you have access to a drive-on lift...

...just put your body weight in the seat, and adjust one of them till the pinion angle is right, and the other's bolt will go in without prying. You could probably accomplish the same thing on ramps, but making sure the car is level would be much more difficult.
