I want tp replace my stock front and rear seat in my '71 Blazer with a more comfortable and modern seat set. The front seats are going to be an easey fit. Therefore the rear seat is what I need to look for first. I measured between the rear wheel wells on my K5 and came up with 47". I've been online searching for and am having a hard time locating something out of a SUV. Anyone already done this? I had been looking at 2000-08 GM models (Suburban, Escalade,Tahoe) but the third row "hip room" is 49.2".
