I actually thought that a previous owner of the Redneck had added these, but when I found them on the Tuxedo in the same relative locations, I thought that they must have come from the factory that way. To confirm this, I removed one from the Redneck and found that the hole has black paint along the inner edge of the hole; if someone had simply drilled it, there should be raw metal visible (which is not the case).
None of my other basses have these extra screws, and because both the Tux and Redneck were made in 1987, I figured it's just some RIC factory anomaly specific to these two models. I would be interested from hearing from the Forum community about this unusual feature.
