I know the 58 and a 2003 have an almost 5" difference in sidewall/sidewall width, but if you do a frame swap, the wheels do fit inside the fenders.
The old trucks tucked the wheels really deep inside the fenders compared to modern vehicles.
I don't know a better source for dimensions than the link above or just measuring it yourself, but I do think the idea has merit and it is plausible to me that it would work.
