Body & Interior
new lock cyls will not work. I have a1974 but your list only goes to 1980
bought new door lock cyls. when you turn the key to the left to lock and return the key to vertical position it unlocks the door again. instead of staying locked and being able to remove key. the pawl only goes on one way. you can only put the lock cyls in one way. you can't put them in upside down. Also from the inside you cannot lock the door w/ the cyls installed.the door latches are the original.the original cyl locks would lock the doors but the key would be in the horizontal position.
