I opened up my dash under panel and saw the wires that go to the ignition swith have popped out along with the plastic round plate that should be attached to the switch end. All the little springs and contacts have fallen out and are lost. Is the ignition switch still available new? Can I just buy the back part with the wires so I won't need to use new and different keyes? How do you take out the ignition switch to replace it? Any advice or diagrams will be greatly appreciated.
