im trying to "mount" a camera in a drivers seat of a CR2 car. I paented it and wanting to make 1st person view of a driving seqyece for a project. i got the AUX cam to lock in the seat, but when i move the car back a bit, the camera starts to fall behind on the axis until it's out of the car all together...how do i lock it in so it stays, and I can film from it with out it moving?
