is there an optimal width between the leaf springs when doing a 2nd gen SAS? All the write-ups I have seen show the rear mount of the front spring sitting just outside the center of the frame but not completely outside the frame if that makes any sense. Seems to me it would be easier if the spring was mounted directly under the frame or completely outside the frame. The axle we are using doesn't have any mounts on it yet so we can set the perches wherever we choose, just wondering if there would be a way to have a bolt-on hanger/shackle or something that wont require welding for the rear mount. The front mount we are making a crossmember that will be welded to the frame. Thanks for the help.
