I have the same issue with the bridge and tail piece holes not being drilled out. Kinda nervous since the neck is a tad loose as I don't want to drill and then accidentally set the neck wrong. Pics on the site showed them drilled vs other kits out there that weren't

Also, the listing said 24.75" scale length, but I measure 25". Have you checked yours? Not sure if that was wrong as well. I'm confident in my measurement, just scared to drill those holes.
