What is the difference between 67 & 68-69 a body steering column

I have a 67 Barracuda. The lower bushing on the 67 is different and as of a few years ago no one makes a replacement. I finally had to get a 68 column. I don't remember the switches being on the column as I have an after market shifter with the backup light switch in it. The 67 A body is a one year only so get a 68/69 column. The 67 doesn't have a lower bushing in the idler arm and it is almost impossible to get the play out of the steering. I am a lousy typist so you can call if you have more questions. I am retired so I am home most of the time 775 883-3446
Thank you, I will call
