Worked several hours on 12 June trying to get T-410s to fit better. Gave up and did some other things then came back on 18 June for another session. While working on 18 Jun I took the parts from the left tank to see how the T-410s fit on the ribs with no sealant in the way. To my surprise the plates sit flush on the forward section (where the rivets are) and are slightly raised on the aft end. This is due to a slight bend in the most forward section of the rib to line up with the holes in the skin. Mystery solved and moved on to cleaning and installing the parts.
