Rangmaster Handyrack brackets

[elektrobank]

I have recently inherited a rangemaster professional 90 and when cleaning, unscrewed the brackets and now cannot screw back in. Conscious to unscrew anything else, is it an easy fix to undo the whole door and dig around? I'd say I'm moderately beginner at DIY so.

What brackets?
