The 2005 Toyota Sienna had a mid-year production change that affects the rear wiper configuration. I highly recommend referencing the application guide books at the store or Googling 'lookup wiper size' to make sure you get the right size as well as the right mount/attachment.
It's tough usually because most vehicle owners have no idea whether they have the "early" or "late" version. Here's what I can tell you:
It appears the "Early" version has a special rear arm. It will appear like its a custom arm and that the blade may be part of the arm. In this case, the closest replacement is a 'Trico Exact Fit Rear Blade' which will snap right onto the special arm (instructions are included with the new blade). Note, it will be slightly shorter than the original but will fit fine. You can find these online.
The "Late" version will have a 16" blade and it will appear to be a standard wiper blade and arm similar to the front blades. I recommend beam blades for rear applications because they don't have the frames that clog with snow & ice. I use Trico NeoForm Beam Blades which work fantastically.
