Any 2000-2006 Suburban or Yukon XL 3rd seat will match...it's just getting the right color & material if you require it to match. The leather and cloth were specific to '00-02 and then changed for '03-06, and were specific to the GMC and Chevy.
As for the Tahoe/Yukon, they actually used a different 3rd row that was split and, I believe, had different mounts because of it. So you'll have to stick with something from a "long" model.
