What is the difference in track width between a 55-57 and a 58-59 1/2 ton? Is one frame more narrow than the other or is one frontend narrower?

Track width 60.5" on 55-57 and 60.75 on 58-59. same frame width 34". The differences in track are in which tire/wheel combination is used. 58-9 is a longer frame forward of the front axle by 2.5 inches. The front fender width is different from 55-57 74.68" at the fenders to 58-59 74.32". There are more subtle differences in frames such as where muffler hangers are and rear spring bumpers and brake line brackets are placed
