Henry J -- Regarding whether the rear seats are bolt-down or sliders, they are bolt-down. If I'm not mistaken, the 60 and 61 Suburbans used the oval-shaped bolt-down plates that limited the seat positions to the factory layout. The 62 to 66 Suburbans used longitudinal channels which allowed the seats to be placed anywhere along them, even turned around 180 degrees. The 63 Suburban I had in the early 70s had the middle seat turned facing the rear with a little table between it and the rear seat, kind of like a dinette in a travel trailer.

Since Dad started with a panel truck which did not have the built-in seat channels, he opted for the easier-to-install oval plates, so the seat locations are fixed.
