I just replaced the front in my 95. There are four studs, two on a side roughly in line with the headlamps/wiper, and then two additional small bolts at the wings ( which you found) and a small bolt in the upper center of the bumper. You might be referring to the license plate holder in your post, you dont need to remove that to drop the bumper.

You'll see the studs if you look in front of the tires. Pair on each side, maybe 3-4" apart.

Careful, plastic is brittle at low temps I found out.
