for a NNBS:
20779111 LH seat adjuster - is what GM said I needed.
the box i got showed a "2596-6539 Adjuster" got it off ebay.
FWIW, the bolts that hold the seat down are like Huge reverse Torx Bit.
I used a IRWIN broken nut/bolt removal kit. You have to have an impact drill, and it does not re-install them massively tight, but it is tight enough, and it works.
it was a smooth job... once I figured out to detach the rear seat back, so i could get a ratchet in there. using the flat 15mm did not work that well. I used a screwdriver to wedge the base away from the seat, to hold tension on the nut as I took off.
the adjuster ships in the "down position" so i just started the front nuts on, and put it in the SUV, and powered it all the way up, then tightened them down.
note the plastic wiring tray will not fit under the front part with the base down, so I kinda flexed it around, and forced it about. I put tie wraps on the wiring tray in the end pics
if you don' t have a 15mm Gear Wrench, this is your excuse to go buy a set. note that is the 10 piece set, which is hard to find, sears only sells the 8 pc set now.
if you look at the pile of tools, you can understand why the dealer charges so much to do work. that's a wealth of tools.
the impact drill is a lifesaver. i work at a desk, so my hands hurt if i do all that stuff manually. that's why I am hitting the ratchet with a rubber mallet, keeps the palm of my hand from hurting for days from tugging on 20 bolts.
i tend to over torques stuff by hand, so that is a nice SNUG tight that is consistent. that is also an awesome trick to get bolts loose, but use a box end wrench.
you don't have to take the seat belt wire off the bracket, that bracket stays with the seat belt.
pay attention to the small brackets, i missed two, but got lucky, and they fit on with the seat installed.
it's a slow job, with a lot of small parts, but it's pretty nice to take your time, not get mad, and do it yourself.
it's a lot of pics, many may be useless, but they should give you the confidence to attack this job and do it right, with no PLO

some idiot had the camera on MASSIVE size, sorry

some random pics:
theres ~160 pics, but it walks you right through the process, which is overkill for some guys, but might give some guys the confidence to do this themself, and that's what cool about forum "how to's"
