Are the cabs for a 57 or 58 interchangeable with the 1960's? Are they essentially identical or are they different? While I'm at at it, are the only differences on the 57's through 60's the front grill, as far as body panels and guages go?

 

The cabs are interchangeable. The fenders, gravel pans and hoods are different also. I am pretty sure the gauges are the same, but the dash ***** changed in color from black to white.
