Picture 1 shows nutplates riveted to the rear centre baggage ribs.
Picture 2 shows the two Bearing Bracket Assemblies. Each has two plates which trap a bearing in a recess between them. I had forgotten to countersink one side first, so this had to be done before riveting. The countersunk side has to be flush to sit against the baggage ribs. I was pleased to see that the bearings were free to move, after squeezing big rivets adjacent to them.
