TFP - Get the camera to follow the rotation of the eye socket

Hey everyone,
I am currently using this script from Kris wich allows me to get a true first person game mode.
Since I changed his skeletal mesh, animtree and animset and replaced it with mine, I notice that there isn’t any head bobbing due to the fact that my eyes socket doesn’t move side ways or up but on in a rotation movement. I would like the camera to follow that rotation if possible. The code is available in download and I haven’t change anything but the things I said earlier.
If anyone could guide me, that would be greatly appreciated. =)

Thank you!
