If a guy is willing to do the work and can get his hands on another set of fenders one could always widen the front end. I have been thinking of doing this to my 56 since I noticed that the twin rear axle TF trucks have wider fenders than the ones with singe rears. As I studied the front fenders I figured it wouldn't be hard to modify a set the same way and it is really hard to see the change. Study the AD body lines and see if this would work on them as well.
