Silent Radio LED sign, removing the three Green LED arrays

I decided to saw off the three Green LED arrays.  To my surprise, I lost three columns of the red Arrays as well as clock and data.  To get the clock and data going again I had to tap into the first 4015 clock and data in.  To fix the three missing columns I had to tap into the first three outputs of the first 4015 and route them through inverters and resistors to the first three columns.  You can see those mods in the picture below.

Then I also added 82 ohm resistors across the 100 ohm resistors to get a little more brightness.  They can be seen in this picture.
