I put the screws in to hold the lower baggage area seperater - fingers crossed I won't have to take them out and put them in too many more times. I also cleaned all the surfaces in the bottom of the lower baggage area before putting in the smoke tank pad and then the smoke tank assembly.
Since the goal is to be able to remove the smoke tank assembly, I really need to shorten the Main Buss screws as they protrude into the baggage area and grab on to the smoke tank wires and the yellow vent tubing.
