I located the mounting holes (2) on the bracket and drilled them. When fully seated these is a gap between the connectors that had to be filled at the two screw hole locations. I decided to use a 1/4 aluminum tube and cut off just the right length to fill this gap. The pictures show this quite clearly. On the pictures these are located at the top of the bracket, between the bracket and the upper connector. This arrangement holds the connectors firmly in place. Installed the barcket with the wires and connectors on the right side of the radio stack. Had to drill two #19 holes in the bulkhead.
