Shot the 6 AN470’s at the outboard end of the flap brace to spar. Clecoed on the right lower outboard skin and match reamed to #41. Used air cleco gun to shuffle the clecoes around while reaming. Layed out holes on the under wing vent and drilled to #51. Transferred these holes to the template I made a few days ago. Then, I taped the template to the wing skin and drilled thru the holes and thru the skin. Held the vent in place and drilled out the holes to 3/32”, then reamed to #41.
