Bingo, you have the idea I believe. The front fenders will likely never measure the same(to ground) for any truck. The suspension should be squared(level) with the ground, and the front lower control arms are easy to check and set. I've argued with members who care more about the looks than the handling(suspension).
My 98 Mountaineer is dead level in the front suspension, about 8.5" from the ground(center of bolts). My fenders are about 3/4" different in height, and no one ever notices, I don't look. One side looks slightly lower than the other, but no one notices it.
Raise the front with the tires lifted, little weight on them. Crank the adjuster bolts up a long way, and remove the jack. You can lower the truck with the bolts without the jack, so try to guess higher than needed to start, crank the bolts in a lot. Roll it back and forth, then loosen those bolts to settle the truck to where you want it, then level the control arm bolt heights with the adjuster bolts.
Remember to have an appointment for an alignment before turning those adjustment bolts.
