Looks like the 43-967 springs are thicker.
In general, thicker springs means more capacity (and more lift), even with less arc.
Lots of lift kits have springs that are "shorter" but give more lift just because they are thicker/stiffer.
I'd guess the 43-967 springs are what you'd want for a 91-97 Explorer for either slightly more lift or the same height as stock depending on what they're going on. Obviously they'd give a tiny bit more lift on a 2-door Sport than a 4-door.
If you're putting these on a 2003, you may want to get the springs made for that vehicle rather than the 1993, since while the springs may be similar in width and length, Ford changed them many times over the years and you will get a better ride and overall a better spring if you get one tailor-made for a 2003 rather than to the specs of a 1993.
If you're having new springs made, you can always ask them about making the springs thicker or giving them slightly more arc if you want a small amount of lift built into the springs.
I'd say call or check out Atlas Spring in the link above, you can probably get what you want from them, and even drive to pick them up yourself rather than pay for shipping across the country.
