If nobody responds, send a pm to 05GTO. His name is Randy. He's pulled the rears out a couple of times at least to route wiring, etc. As for the bottom, I think they just pull forward and up -- but that's just a vague recollection.
If you remember, let me know what the sides and back of the rears look like. Thinking a getting a couple of them from the junkyard, getting the sides and back upholstered, then tossing it into a wooden frame for a chair in the corner of my office. Either that or a front seat or two. Think it'd look pretty cool with the stitching...
