66 mustang ignition problem
So getting my 66 stang back up and running after it has sat for about 10 years. Started by getting old gas out, putting new gas in, putting coolant in radiator, and a new battery. Went to try and turn the car over to see if it would start and my key wont start the mustang actually. It wont do anything. I cant get it to move to ACC or on position. Not really sure what to do at this point. The ignition switch was never a problem when I drove it before, so wondering if anybody has any tips. Thinking Im going to have to replace the tumbler and ignition switch, but not sure how I can get it out since I cant even get the key into the acc position. Any help would be much appreciated! Cheers!
