Here are the great example of how this kind of damage can be repaired, and how I do it frequently. It`s a pretty common case, and if there was no amateur attempts of reparation it can be easily glued back and guitar will live long and happy live ( if it dont break it again by your own fault ofc :) ). Despite popular belief after proper gluing barely nothing change withing the guitar (in case when parts fits perfectly with no missing chips). And in addition to all of that many of guitar manufacturers that makes acoustic guitars and necks with angled headstock dont use one big chunk of wood for neck. Almost all of them are already glued from several pieces of wood in the name of stability and cheaper production process.
Beside neck repair here I show one of examples of how crack can be masked. There is a lot of ways to do it, starting from not doing with finish anything at all and finishing with full refinish of damaged part when it`s really worth it.

"Gluing the truss rod" and "Truss rod nonadjustable now" first of all you can't do a metal+wood bond with Titebond, bc it's dont fit for this purpose. Beside that truss rod here is in polyethylene film, and it dont really gluable at all. Second the nut located on the other side, and look first p, in case of any further questions about gluing the truss rod.

Also we launch YT sponsorship, and already have educational content about fretworks.
