Short story is that I ordered a Wiper Motor Linkage Assembly for my 2013 Toyota RAV4, I gave it to the mechanic to install and they told the part was wrong and it is not the right size for the car.

My question to more experience Toyota users is that, is there a difference in size among the different models of that RAV4 that year (2013), did I order a wrong part, or did they send me the wrong part? All the numbers and manufacturers details seem to be in order according to the site, this is Rockauto.com, I just put in a return order, but I am not entirely sure if it is a wrong part or I ordered a the wrong size. Conversely, in their menu, they only have one option for RAV4 makes for that year, (2.5L L4)
