Put in one of these today. Book gives 8.5 took about 3 hrs. The 98 model is harder to do. I started by taking the hoses aloose. Then move the blower resister. Look down in there---unscrew a bolt going the firewall into the blower housing. There is a stud coming through the firewall in the middle. Takes 7/16 socket--take care of that one. Now go to the inside and take the whole dash and put it in the backseat. Scews at the top. A 10mm headed bolt on each side. Drop the column down. Need to do some unplugging. Remove glovebox and you got a big electrical connector-use 7mm socket. A vac. Connector. Get some slack going for the ant. Cable. IMPORTANT-- Take aloose one connector at bcm(plastic box in middle). The one at the top going to dash.I almost pulled it by the roots. After pulling the dash back a little you will see a connector on driver's side with big wires---get it. And get the ant. Cable out the back of radio. None of this bad to do. The housing has a 10mm headed bolt at bottom and two screws coming in backwards through the firewall. Undo the bolt. I used a hammer and big screwwdriver on the other two underthere. Yank back-do the core. I could do three of these in one day and I'm getting old. Didn't take pictures sorry. Got a late start on it today and to my surprise finished it. If you think this one is hard better run when a jeep comes in.
