hay there!! welcome to the garage! "D
the cabs are basicly the same but the problem you'll find with that switch is that the hood hinges are different and the mount holes for'em are slightly different, so yes, it can work, but expect to have to struggle to get those hinges mounted so the front sheet metal all fits well - might be as easy [and no more spendy] to fix the pillars and corners as there are good patch panels available for both areas, and the 58 cab prolly will need help there as well
good luck w/ it and let us know how it goes
Bill
