I knew the rear bench seat that came factory with the K5 was not gonna work for my family of 5. Being only lap belts with no head rests and various other things set me on a search for a bench seat that I could replace it with that would give me what I needed:
- Split folding
- shoulder belts
- seat belts incorporated into the seat itself (no extra mounting needed)
- durable (preferably leather)
- narrower than 50 inches
These parameters narrowed my search down to the third row bench seat out of late model GM. They mostly hit the requirements but the one that got it done for me was the Cadillac Escalade ESV.
I searched and searched on craigslist to find what I was looking for at a price that was reasonable and my patience paid off. I found mine about a hundred miles away and met the guy halfway.
I built some brackets to integrate the hardware from the new seats into the hardware in the truck and we were gold!
