but its good to move it forward and brace it better.
X2. It all depends where you locate the spring hanger. I think most of us here will tell you, the SAS is well worth it if you can afford to do it. If you move the spring hanger too far foreward you will need to move the PS box. Also like Aaron said bracing it is important too. Marlin sells a cheap little kit that makes mounting it real simple and strengthens it a lot. all you have to do is figure out where your spring hanger will be, then hook up the high steer and cycle your suspension and see if the tie rods hit. leaving the steering box as one of the last parts of the SAS is a good idea because it will allow you to see just where you need to place your box.
