Struts 2007 Yaris

[cort21]

My struts are needing replaced on my 2007 base model Yaris, and I have a friend who said he would install them for me if I got a set of quick struts. I have ordered 2 different sets and in both cases my friend said he couldn't get them to thread completely, because the bolt at the top of the strut isn't long enough. I find it odd that I've ordered 2 sets from 2 different vendors and they both have this shorter bolt. The attached picture shows the difference between the old and new struts. Did I really receive faulty struts or are they just not being installed correctly?
