MM/Fender headstock thickness

[rubis]

Hi

I am in the throes of my first bass build and need some help, can anyone confirm for me the thickness of the headstock on a Stingray or a Fender bass, I am guessing it will be 15mm or 5/8"

thanks

I find them usually between 9/16 and 5/8. So yeah you are in the correct ball park.
