While working on the right side console, realized I was not going to be happy with the clearance (or lack thereof) from the wiring harness and the backup battery. I decided to move the backup batter inboard so there would be sufficient clearance to prevent the wiring harness from chafing against the battery.
I drilled out the blind rivets securing the battery brackets to the cabin floor, then used the brackets to match drill two new rivet holes in board, shifting the brackets inboard. Riveted the brackets to the cabin floor, which is now ~ one inch more inboard, giving plenty of clearance for the wiring harness.
