Help with bathroom downlights

[sjm]

I have a customer whose previous "electrician" installed tiltable LV downlights in zone 1 right above the shower, it's a low ceiling. I have to replace these with IP rated downlights. My problem is that the cut out is 78mm and the biggest cut out I can find is 74mm, but the flange is not big enough to hold itself on the ceiling. HELP! Anyone got any ideas please.

Is this bathroom downlight any good? It seems to tick all the boxes.

Thanks KCElectrical that would seem to be just what I'm looking for.
