Yes, Get the dimension from a 57 truck from the front spring hanger bolt to end of horn. Get it from three sources before cutting.........or your own measurements from a car show or meet or one you see somewhere.
Assy Manual says 9.48 from end of horn to center line of radiator bracket. Not sure what year yet. Still checking.
178.05 over all frame length for short bed. Drawings dates Dec 54 and Jan 55. Last revisions 1-26-55. So they are not 58-59 frame dims. That mans they are the dimensions you want. Confirm by some other method as stated above.
If these dimensions give a cut off of 2"-3", that's pretty good confirmation. If not, let me know.
Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
