I have an email out to support, but am thinking through the ramifications of my latest mistake and wonder if this is salvageable without part replacement. This is from the fuselage page 25-05 and is the bearing bracket.
It is a thick piece, and a universal head (ad4) will be going in that hole. The backside is countersunk and behind that is another thick spar piece. The way this happened is that I prepped two chapter's worth of parts and didn't look closely enough at which of the web holes they were talking about for this piece. Luckily this is the only real mistake.
