To the OP: You'll probably want to do some checking on that explorer rear. When I Was searching for a rear axle recently in the yard I noticed that on some of the explorers the sway bar was installed behind the axle rather than in front. Don't know how the 94 Explorer was set up.
Like I've said to others before, saying it again for reference and maybe save someone some money. Get a aftermarket front bar if you want (don't know much about interchangeability there), but when it comes to the rear please save your money by checking the junk yard first. You can get a 1" rear sway bar out of a Ranger or BII (maybe even explorer). They are as big as what you'll find aftermarket, and all you have to do is get a new set of bushings (if even that). Have to do a little searching, and have a little patience but they can be found.
My Experience:
The 84 Ranger in my sig was my first vehicle, it came without bars front or rear. Drove it for years like this, and I'm a very spirited driver. Two words: "Body Roll". Something as simple as a lane change would feel like I was turning at high speeds in a boat.. In all those years I never missed a sway bar didn't know the affect it would have either. Beginning of last year I installed the 1 1/4" front bar, and WOW!!! The truck is already 10000000000000000000000000000000000000000x better. Still get some roll on the rear but the front is great. I've currently got the 1" BII bar I mentioned above waiting to go onto the rear axle, I've just got to find the proper bushings. Ordered the set I believed to be the right size, but they were listed wrong, compared specs to find the right size now just got to order them. Once I get the rear bar in, install my 3" drop beams, flip the rear shackle and install new springs all around I fully expect this truck to riding like a boat to like it was on rails. Sure I'm sacrificing ride quality some but that's exactly how I want it to handle.
