I am not to sure what you guys mean. We have all run into stuff like this and have answers but I don't have AD, I have TF. Are you using 55.1 or 55.2 rear. I'm sure you know that 55 was transition year from closed to open drive shaft. I guess I just don't know what this means "Since the center of the leafs or offset forward of center line of the wheel wells"??????????????? It does not matter where the center of the leafs are or where the wheel wells are, put the new axle tube in the same place as old axle tube and adapt spring mounting to it. Then no troubles with drive shaft length, axle to spring geometry, ebrake cables or anything else. Just curious: why changing from 53 to 55, would not another 53 be easier? Old one is broken, new one is free?
