Hey all, I have the Q-logic kick panels in my 98 and they sound great, no rattle or other problems. But, installing them was a *****.
First, you have to move the parking brake over. I was told from someone at Ford, that the parking brakes from pre 98 1/2 explorers were bendable because they were made from a straight piece of metal design. Simply, like a straight piece of steel, that could be easily bent. But for some reason the 98 1/2 and up, the cut of date was march of 98, they went to a bent steel assembly. The parking brake leg instead of looking like a straight steel bar, looks like one of those holders in a Scrabble set, like an L. This is what I was told. Nonetheless, I had to remove the whole brake assembly, hacksaw the metal off, and reweld it with the proper distance so that it would not mash into the panel.
In retrospect, I might not have gone through with it, but I just had to have them. The reward is sweet, though. I have a pair of MB Quart 5 1/2s and they are sweet. They don't rattle or sound crappy. They are well worth the trouble. I got the panels for $130 from a special sale of some site that JTang referred.
