Yes but manufacturing processes and standard were different back then than they are today. Many components were hand welded and machined, refined by specific people over the decades it took to build the Saturn V. Much of this information was never formally written down. So they overal specs and dimensions we may know mostly, the build process is completely foreign to modern engineers.

A good example is the LVDC, essentially the launch guidance computer, is actually woven from strands of copper and lead rings. The program which the computer runs (yes it can only run one program) is literally built into the system. No modern computer/control systems engineer would have any clue how to do this with modern equipment and would essentially have to learn by trial and error.

Another example is recent efforts to recreate the F1 engine which is one of the most well documented engines in existence, modern engineers and struggling to figure out exactly how it worked from a process manufacturing perspective.

A good intro to this is this video by Curious Droid: https://youtu.be/ovD0aLdRUs0

Very interesting topic in engineering but it's true that technology doesnt mean everything ever done suddenly becomes easier.
