Why won't my car come out of park?

When I tried putting my 1976 Ford Gran Torino into neutral to push it back because it doesn't stay running it wouldn't go out of park I even went under the car to put it into neutral because the linkage is messed up and it still didn't go out of park can someone please tell me what's wrong?

Is the ignition keeping the gear shift locked so you can't shift it? Try putting the key in and turning it so you can unlock the shifter.
