I also scored the front 2 buckets, the second row, and third row seats from a 2012 Tahoe LTZ? that was totaled for $400.
I'm not sure who's thread this is, please give credit if you know (I found this pic on google a while back I'm sire its on here though) this is what I'm thinking for the 3rd row seats in the back of the k5, and buckets up front.
