I searched but didn't really come up with an answer on spacers for a SAS and how to deal with the 3" difference between the ifs rear and the straight axle front. The obvious and simple solution would be to put 1.5" spacers on it to set the wheels out but this seems like it would put a lot of stress on really important parts. I know the IFS hub swap is common, but any way you widen it its still adding stress and leverage to the trunions. Is it common to add spacers? This rig wont be wheeled hard as compared to some of you guys but it will see some action.
