I doubt you have a later bed, it wouldn't match the 1957/60 cab lines, wouldn't fit properly as there would be a large gap between the cab and bed due to increased wheelbases over what was available 1957/60, but...
I'll betcha if you have an auxillary or saddle tanks, they're aftermarket, cuz there was no such thing available from FoMoCo back then.
