So I finally got around to getting a 14 bolt FF axle for my 1949 1-ton. I am currently in process of relocating the spring perches to fit my truck. My problem is if I keep my 2" leaf springs and use 2"x 12.5" u-bolts, the old 3" axle u-bolt saddles with the 2" bolt hole spread will not fit the 3.25" 14 bolt axle. I cant use the saddles that were on the 14 bolt axle due to the bolt spread (3" between holes I think). Has anyone swapped axles and what did you do to counter this problem?
