integrated door sliding kit

Hi ,I’ve just ripped out old kitchen with a mate, ready for new one in the new year. We’re re-using old whirlpool integrated fridge freezer, but my ‘mate!’ unscrewed the 4 door sliding kits from the side of the fridge freezer doors and left them attached to the kitchen unit, which is probably somewhere on a landfill site now. Does anyone have any from an old fridge freezer they are throwing away before I throw HIM on a landfill site. Thay attach to the fridge doors by 2 self tapping screws and consist of a L-shape bracket which slides on a plastic strip which is attached to the kitchen doors
