I remember 1970's Fenders when you could not give them away.
IMHO, there is nothing fundamentally wrong with 1970's Fender necks that some fretwork will not fix. Fender used decent quality maple in its necks, even then. Bodies, again, IMHO, are another matter, espcially ash bodies which were often made from some tone-free wood that was rejected as too heavy for shilleaughs.
I do not care for the Highway One necks at all, but that is because they are a sort of "fun vintage" that does not appeal to me. You may feel differently and all that.
