The GM Full Size SUV is built on one of two platforms. The short wheelbase includes the Tahoe, Escalade, and Yukon. The extended wheelbase includes the Suburban, Yukon XL, and Escalade ESV. Due to this difference there are two distinct styles of rear seats. They're essentially the same seat, but the bolt mounting points are different. These seats are not interchangeable.
