Yeah, that's what I would do...take some careful measurements, and then try to find any 2005-2007 Escape, even if you have to go to a used-car lot. The external dimensions should be significantly different. The part numbers I gave you in another thread show that there are definitely different parts for the 2001-2004 XLS, the 2001-2004 XLT/Limited, and all 2005-2007 models.
The Trademotion/Parts.com database, while pretty extensive, is also full of bugs and incomplete information. For example, the Mountaineer was listed under Ford. I e-mailed them about a year ago, they changed it to Mercury, and then four months later, it was back under Ford. And they STILL don't have parts info for the 2008 Escape and Mariner. I gave up with them.
