Fabbed the two reinforcement angles and the shims.

Used the support bracket to locate the bottom hole.

Drilled out all the rivets between the top and bottom holes.

Then match drilled the shims.

Countersunk the 426-3 holes.

Bent the bracket slightly to match the angle of the tab.

Bolted it in place and drilled the hole in the Tank tab.

Still have to rivet the reinforcement and shims in place.  I'll do this after I remove the wings.
