Did you remove the wires on the seloinde. If not sometimes these wires are pretty tight and leave no slck for pulling the starter out. After that the only other thing that really ever holds the starter in, which I do not think your vehicle has, would be a cover going over where the gear on the starter is. These covers somtimes sit into a groove on the starter. The only other thing I can think ofis are you sure that there is not smething in the way, like the radiator brace or something else, on the other side of the starter that is not allowing you to pull it back restricting your movement. Thanks for the question.
