Here is a 70s Fender Musicmaster bass neck for sale:

Probably from the early 70s. Frets are okay, truss rod works properly, no apparent playability issues, I played on it for a few months and enjoyed it. Known issues: no tuners, string tree or nut; the finish is worn off the back of the neck; the tuner holes have been drilled out for Hipshot Ultralites. Overall, a nice player neck as is or also a restoration candidate.

And here is a 70s Fender Musicmaster bass body for sale:

Probably from the mid or late 70s. Known issues: obvious refinish, extra holes from a too-large pickguard mounted on it previously, holes drilled for through-body stringing; one ferrule mount on the back is off-center from the other three; extra strap hole on top side; black marker added in spots.
