I'm not sure but I've had the bottom seat out and that just popped out with a lift in the front on each side of the seat. The battery is in there so they're made to come out easy. From there the back of the seat bolts should be visable and you just remove them and you should have access to all belt assemblies. But the real reason I wrote, there was a recall on 1995 rear seat belts that I found on the net. Check with the dealer and have your VIN number available and maybe you'll get them done free.
