I picked up my Yukon a few years ago. It was in relatively decent shape, but heading towards thirty years old it needed some refreshing.
I tore things apart to work on updating the interior of my Yukon - recovering the headliner, putting in sound mat, new carpet, and other upgrades.
To start, I found a pair of GMT-800 bucket seats for a good price and made up brackets out of TS2x4x1/8 to mount them. The brackets mount to the original bolt holes in the floor pan with holes in the tops of the brackets to reach the bolts. Then the seat rails bolt to the tops of the brackets. It took several iterations of putting the seats in, marking things, pulling them out, drilling the holes, and so forth to get everything lined up but it all worked out perfectly. I started by placing the console to get those holes in the right place. Then the inner seat rails mount to those same bolts, so that enabled me to locate the holes on the outer rails. Sitting the seats right on the floor pan put them much lower than the original seats (the GMT-800 must have higher corrugations in the floor pan), so the 2" of the tube steel put them at the perfect height.
I like a firmer seat with some side support, so the GMT-800 seats are much better than the original bench (or the GMT-400 buckets).
