A few weeks ago I noticed that my Super Bee has the speaker holes in the package tray that were not symmetrical. I remember thinking how "odd" it was.
Then I saw phtos of some other 1969 cars where the speakers holes were the same size & direction.

Was there an option difference for this or just different production plants?

Example #2:



1969 Dodge Super Bee A12 (440 Six Pack, 4-speed, Dana 60 4.10)

1972 Plymouth Road Runner (400, 4-speed, 8.75" 3.23)

1974 Plymouth Duster 360 (360, 4-speed, 8.75" 3.23)
