The '69-'72 4x4 trucks also use 2 1/2" wide leaf springs and the 2x4 use 2" wide springs. Longhorn trucks are 2 wheel drive but they have 40.5" spring centers and use 2 1/2" springs just to mix things up.
Not a '67-'68 guy so can't speak to what they had but I know the springs are different.

Weren't the 73+ axles also wider than the 72 and down?
