tilt interchangeability year-to-year
 

What year tilt columns are a direct bolt in replacement. i.e. does a 71/2 tilt fit a 69/70, or even a 67-68, for that matter.

What are the differences, if any? i.e. does it fit, but has a different gear shift selector indicator window, i.e. box vs. little lettered window, etc etc.

Thanks, just thinkin...
