Cool! I keep wavering between going that route vs. getting 4 suspension seats.

they are on eBay as Tahoe 3rd row universal seat brackets.
my plan was a suspension seat bench in back originally. what sold me was integrated seat belts and they still fold up and remove easily which is way better than the original.
