The 3" was only for the Gen I to Gen II conversion. The Gen II Explorers only have the 5" flare, which is what I ended up getting.
Perry's only had the 6" available. They make a 3", but only if they get a bunch of orders in at a time, so no luck there.
I went with Fiberwerx since it was an inch smaller than Perry's. Both places are $300 for the front pair.
I also got some wheel spacers, and that will help fill in the extra space in the front. The tires are about an inch outside the fenders right now, so it won't have too much free space under the fenders. I'm also going to crank it up another inch or two with a t-bar twist, since they are stock height right now. That should also make it look better.
