Fellow seat builder here! I do the Escape/Mariner/Tribute seats. Same plant that used to do the Contour/Mystique seats. If you run into any trouble, shoot me a PM and I can ask some of the old folks at work about it. I'm sure they have a wealth of info about these seats.
I did find out a while back that the SVT seats were hand built off the assembly line. I also was told that they were a PITA to build.
BTW, What company are you with? I'm Magna.
