This is my first post here. I searched the archives, but could not find anything on this topic: The 1971 Barracuda "Keyless Door Locking System" was listed as standard on the 1971 Barracuda. I would like to confirm that this feature was new for 71. A couple of 70 Barracuda owners have told me that in order to lock the doors, they must use the key. If true, can the 1970 door lock assembly be converted to work "keyless" like the 71?
