No nuts holding them if I remember right. Maybe your threads are stripped out.
Try wiggling it with a pliers to see if it will wiggle out. Did all the other ones come out ok?

the threads have rusted. Drill the bolt out.

I had mine out a while back. If I remember correctly there is a "plate nut" welded in to the floor.
That is a common place for rust. If it is spinning, it probably broke loose of its weld.

There is a nut "underneath" the channel.........suppose to be held in place with a "clip". The clip has rusted which allows the nut to spin. Ask me how I know. I'm glad I was trying to remove a seat in the junkyard. Never did get the nut off the end of that bolt; of course, I only had my junkyard toolbox with me.
GOOD LUCK.

Without power tools, it would be a tough job. Would a crow bar provide enough leverage to pull out the floor mount?

I had to use a power chisel to cut off that back bolt last time I did this. I suppose that a proper chisel and good hammer might work for younger guys....

I guess this is a stupid questio. How do you drill it out?? Just use a drill and a drill bit to "destroy" the bolt??

I'm looking up info on how to drill out a bolt, but they all talk about bolts with broken heads. The head of my bolt is still there is just that freaking clip/nut still holding it.
Any ideas??

Here are a couple of options:
If you don't care about the floor pan such as a car in a pick 'n pull or a true parts car... undo the front bolts and start rocking the seat forward and backward (about 45 degrees) and eventually the sheet metal will crack and you can lever the seat out. The method is also used if the seat is "frozen in place" (track is rusted or the seat won't move fore / aft). This ripping out of the seat is not recommended if you want to keep your floor intact. If you do care about your floor pan, then use a wedge such as a screw driver under the head to put pressure / tension on the fastener. Then use a wrench to remove the bolt. If the nut is stripped out of its weld cage, then drill it out... all the way through the nut and the floor. When reinstalling the seat you'll have to resort to a bolt through the floor which is attached to a nut. I'd recommend a stainless bolt with a stainless castle nyloc nut. This way it won't rust. Use some kind of sealant on the hole you put thru the floor.

If I remember it is not blind from all sides. Maybe dremel the the head of the bolt off. I need to go look at mine tomorrow. I have forgotten what is there.
