I've got the passenger bucket out, but after removing the 4 nuts from the bottom of the driver's seat, it still won't move. It appears the front two and the right rear corners are free, but the left rear corner of the seat is still stuck solid. Is there something else down there holding it or do I just need to pull harder?
Might be rusted to the floor... Should come loose with the four nuts taken off. Only other thing is maybe the floor is bent a little and the threads are getting stuck... It isn't even moving a little? Try some penetrating oil...or tap the bolts from the bottom (if not that one under the e-brake bracket that is so hard to get to).
are you talking about the rear nut on the outside, closest to the door? theres the nut there but between the nut and the floor is a metal bracket that either holds a fuel or brake line in place. that little metal bracket slips up over the stud of the seat in that corner. if you dont pull it loose from under the car you wont be able to get the seat out. had the same problem pulling my bench out last summer goodluck
