For use this (Sparkfun) 74HC165 board you will need make modifications adding resistors - what may result more laborious/difficult than make an new board be scratch using the correct layout (e.g. with OSPark PCB), see in the picture:

BTW - This PCB layout is not the one used by Sparkfun, is included in MMjoy2 documentation and already included 10k resistors, but for work OK need the additional modifications noted in drawing.
