I just bought a door lock and ignition cylinder set so I won't have to use 2 keys. The ignition cylinder is easy to remove. Does anyone know how to remove the door cylinder??  

If you have a 64 1/2, 65, 66 or 67, you need to remove the door trim panel and go inside the door. You will need to remove the clip on the connecting rod where it is attached to the cylinder arm. Slide this out of arm. Then there is a large clip that holds the cylinder in the door. You will need to remove this and the cylinder can be removed. Assemble in the reverse.
