converting 63\" 1/2 tons to 63\" 3/4 tons Anyone have a clue on doing this? I have a set of 1/2 ton 4x4 63" springs in the driveway. They are 4 leaf + overload, the 63s on my 97 3/4 ton are 5 leaf + overload. Anyone know where I could source that extra leaf? Or if its just that simple? I'm thinking about selling the 97 and going back to my Suburban, and seeing as my burb has 56s and would be pretty damn easy to swap over to 63" springs I would like to, but the burb is 3/4 ton and would be a hauler.
