Hey Jeremy,
I just had adjustors added to my sub-frame. They weren't tacked into place untill an initial alignment was done so that they could be set to the same range. The adjustors have a total of about 2.5 degrees of movement. You'll want the toe to be just a hair inside of toe in, say 1/16th - 1/32nd, the camber will vary depending on your tire and how stiff the side wall is but -1.5 to -3.0 degrees should cover most camber situations on the rear. If you weld the adjustors before a base line alignment, you never know what you'll get, may as bad as one side not being able to be aligned correctly. Good luck,
James
