on the steers cut off the blocks between the leafs and axle. this will lower it a bit, you can also modify the axle by making the spindles higher. For the drives cut the airbags and the support for the torsion bar. The bags on the Low leaf suspension are smaller that what is on the model.Don't cut too much at the start, take your time and get things where you want them to be. Again on the steer axle you can bash 2 front axles to make the spindles sit higher and even out the stance. That is my 2 bits. If you need some pic's or guide lines check out the Eaton website, they have fairly good parts drawings. I will post a link tomorrow when I'm at work and am on the site.
