Caple intergrated larder fridge

I have a Caple intergrated ‘under’ larder fridge. CBL3. The bottom bottle shelf has been craxked for a while but now has broken completely! Found another one of those no problem but the lug on the inside panel of the door holding it on has also snapped. This is far trickier to find. Can you even buy this panel as a spare part? Thanks in advance for any help!
