I have a Fiori distributor (two actually, but keep that quiet as that fact may quell prices if I sell them )
Also bought a Ford Escort reman from US, but it came a little naked, looks good fit, so possibly same body as the Ford/Mazda one.
The o ring seal gets in the way of fitting in the EJ22 housing. I suspect remove o ring would be perfect, just seal with silicone sealer/gasket maker.
Use enough correctly, maybe no bracket required
I spied a mid 96 Courier dizzy still in it's own Courier and I recall it had side entry cap, which is always good
