Holes were covered / welded with pieces of sheet metal on the inside of the panels. Then filled with super bondo supreme stuff on the outside. Interior sheet metal patches primed and covered with silicone.
Tip - if you ever do this - don't s*** can the original drip rails like I did. Grind them down on the top edge to the metal for uniform appearance and paint black or to match the body. The OEM replacements are pathetic pieces of rubber and fiber with an internal strip of metal. They won't rot and chip like the originals, but they are a PITA to get on and stay on.
