The third row, by the seat of my pants. I copied from pictures, the angles and bend diameters from a non-correct year middle seat. I just widened it to be within so many inches of the upper corners and enough to clear the wheel wells. I'm happy with it and spent somewhere around $40 in materials. I could've done a little better with the sheet metal, but my mistakes are where most folks won't be looking. The lessons I learned made for a better job on the middle seat.
The middle seat, I copied a middle seat I had. I believe it was for a later year Suburban but I'm not sure which.
I also built both of them to use 3/4" plywood for backing, covered with 3" of foam, covered with the covering of my choice. I believe the foam and the Naugahyde was the most expensive of all the materials I bought.
By the seat of your pants rear seat frame looks like a stock factory seat frame. And a heck of a lot cheaper.
Good Job, Thank for the photos.

We built a jig based off of the original frames for the middle & rear seats & we even recreated the original waterfall design of the seat backs on the ones we made.
What is the "original waterfall design of the seat backs"?
It is apparent in the photos above?
Thanks, Tim
It's where the lower portion on the sheet metal seat back is welded to the frame. The waterfall makes the frame stronger & helps to prevent the seat back from rattling.
