You might want to check and see if the truss rod nut has backed off. I can't imagine so but it may never have been snugged up either. You will be able to tell if it is loose if the washer is floating around (you can rotate it, or it rattles).
Truss rods don't adjust action, per se but do control stiffness a little bit. What they do mostly is draw back or relax the bow of the neck. If the nut was never tightened, it could make for a sloppy neck. Don't crank down mercilessly on it. Once snug (back it off first if in doubt)ther will be about 180 degrees (half turn) of adjustment tighter.
I have never heard of refitting the bolts but that might be a re-issue issue. My '69 has the thicker baseball bat neck and is pretty rigid.
Visit some music shops and chat up the luthier if in doubt or unfamiliar. Again, I've bever heard or seen a neck mounting mod mentioned by owners or sellers but i do live under a rock and may be that unfamiliar myself. ;)

: Hi,
: has anybody experienced a lot of neck movement on their Dan Aemstrong plexi guitar?
: I have a smoked finish 1999 re-issue and, like the 1960s originals, it has a weak neck which moves a lot.
: Ampeg product support said the solution was to use smaller bolts, fill up the holes in the neck and bolt it from the outside.
: I've seen two techs and they said it's not the neck joint that is the problem, but the neck itself which is moving.
: Any ideas on how to strengthen the neck?
