It is possible that they are Tooling Alignment Holes used in the Body Welding "Jig" cleverly disguised as Drain Holes, and can be used to drain water, but until then, are plugged to keep the dirt, water and exhaust out.StudeRich

As mentioned by Studerich, these holes served more than one function. During the design and manufacturing process, engineers strategically place designated dimples, ridges, and, yes...holes...for good reason. The ridges give strength to sheet metal panels. The holes, for stamping molds, keep the metal from moving around during the stamping/draw process as the "part blank" is being exposed to tremendous forces when it is being shaped (stamped). Stamping molds use hardened steel "dowel/locator pins." Without these dowel pins, the metal blank has the potential to shift, and for the required accuracy of critical parts, could be disastrous.
Properly designed, the intent of the dowel locators can then be further utilized to align with body bolts, or located in low points to allow moisture to seep out. If you will note, even where the rubber plugs remain, they will move around a little in the hole. That will allow water to escape while keeping dirt and debris from entering. They don't always work to perfection, but, for their intent, have proven adequate.John Clary
