The outer fender will fit w/o problems, but the issue is the inner fender. Personal experience. The front portion of the inner fender is extremenly different, regarding core support area and grille/parking light area. I found a perfect pair of '56 fenders (sold today), and intended to switch the inner fenders. To experiment, I bought a junk fender to work with. Studebaker did a great job of spot welding the inner and outer fenders, it is a real effort, with so many holes to drill out the spot welds, and those in the front portion are very hard to get to,that I decided to find '55 fenders, which I finally did, by purchasing a parts car. Believe me, it can be done, but it is labor intensive and would be difficult, though not impossible to switch the inner fender. Review a parts manual, to determine the many differences in the front section. At that time, I was new to Studes, and asked many old timers, which gave me many differing answers, innocenly. For what it is worth, I was suprised that many did not realize the extreme difference. tempestan
