Mag Stick Plus in 4 way still hits 2 at the same time

[Soundwave]

It uses a square shape restrictor and it turns just fine but in 4 way mode, I can still rotate the stick around and it appears to me that it will still hit 2 switches at the same time. I haven't been able to test it in a  4 way game yet since I'm still working on my cab but I wanted to know if there was any other restrictor plates I could replace it with or will it legitimately act as a real 4 way once I actually use it in a game?

I also have a Happ competition stick, is it possible to swap parts so that the Happ stick can be used to switch from 4 way to 8 way or are they incompatible? Mostly asking so I can have more leeway to move the stick. I knew beforehand that Magstick is a bit tight but really wanted the switch design.
