That's correct. My own bass is early to mid 1974, and it has a 4 bolt neck, and they bought out the 3 bolt neck, bullet truss rod jobbie from mid to late 1974.
It's also very common for Fender to use old parts off the shelf. This particular bass for sale has a 1973 neck plate, long G screw (like mine has). So assuming the parts are original I would say this bass was put together in late 1974 IMO. GLWTS
