November 28, 20177 yr comment_536064 I have never seen a door without a side beam. I have a 69 Z but haven't checked that one. I just removed a couple doors form a 72 and both had the smaller beam. I believe that they changed in late 72 or 73 to the heavier beam. I have an early 74 door that has the big beam.
