Today I installed the end ribs into the tank. I used doubler plates on the inside of the nose of both end ribs to get a better seal. The real pain was riveting on the tank support bracket. The bracket had to be riveted on after the rib was in place since the bracket blocks access to a few of the rivets near the nose. I then encapsulated all the shop heads and put a good fillet on the inside. Not super pretty, but should be leak free.
