Ditto. I've done the last three quadrant swaps (on mine and my buddy's Foxes) in less than 2 hours without removing the seat or carpet, only needing to slide it back all the way. I kind of cheated, though - I took a little hacksaw blade on a handle (y'know, kind of like the ones you'd use to cut out holes in drywall for electrical outlets), sawed off that round little "ear" thing on the side of the pawl that keeps it from being able to be spun all the way around, and with the spring clips off, it all just slides right outta there.
Please, please, PLEASE do not use an adjustible clutch cable when you go to put the new stuff in there. You will NOT be happy when that thing eventually frays out and snaps on you in the middle of traffic one day. Stick with the OEM piece and a firewall adjuster, and you should be just fine.
