i HERC-ed my jeep tub and it was easy as could be. The seats are held down by four bolts, 3 standard hex heads, and 1 star bolt. Now i have an 04 TJ, so there is a small wire connecting to the driver seat for the seatbelt sensor, but there is a clip that is easy to remove.
when i did my tub, i removed everything, including the seat belts from where they were bolted, the rear seat mounts, the center console, the jack mounts, ext. It was a completely bare tub.
Just as a warning, the prep work is backbreaking work but well worth it. a few things i should have done differently...
1) should have preped higher up under the dash and lined the tub all the way up under there.
2) should have taking off rollbar pads, and prepped and lined the rollbars up a ways under where the pads go, so there are no "gaps" between the liner and the pads
3) Wish i would have done a better job taping off around the doors. And I should have removed and then reapplied the tape between coats.
Doing the Liner was a great upgrade i did. I am very glad I did it even though i made the above mistakes. now when ever it gets dirty, taking a hose into the jeep is no problem when cleaning.
