Another stupid Blackout question

I've had Blackout for a while now & I've transformed him enough times to know how best to do it, however I have real trouble with his feet!
You know when you open the sides of the choppers cargo area & you pull out his heels, how are you supposed to do this? I find myself needing to pry them out with my swiss army knife. There isn't some tab that I'm missing that I could have been using to get those annoying little black heels out, is there? At first I didn't realize the Automorph in the knees & just pulled those tabs on the front out, without realizing it so I'm wondering if the heels are automorphed & I've just broken it by doing it manually. As usual the instructions are no help.
Thanks
