Seat, mounting bracket, and pedestal repair and/or replacement

[soulseller]

I'm not totally against replacing the seat/mounting brackets/pedestal as I have a friend who works for a parts supplier and extends me a hefty discount off retail however I don't know that it is new seat and pedestal are necessary, the ones I have are in fine condition, it is only the fact that one of the pedestals is very lose and both mounting bracket/sliders are pretty well trashed.

I don't quite understand the last two posts though, what part of this is going to be a pain, swapping in a new seat to pedestal mounting bracket?

My only real question is how do you remove the existing pedestal from the floor and how do I either re-secure my existing pedestal or a new one if I go that route. I saw reelapeelin's link to the toggle bolts, is that the way to do it?
