If your QuadJoy is 5+ years old there is a good chance that your bottom plastic will crack (plastic gets more brittle with time) when the unit is reassembled with the new magnet holder. The new boxes have a different brass threaded connector so a new Articulating Flex Arm will need to be purchased too (unless you purchased a new one since the beginning of 2018).
