The runners for two drawers in a wardrobe have been removed - presumably the former owner had a problem with them but never fixed it. The only clue as to what may have been the problem is the damage to one side of a drawer and the fact that a small white plastic screw was missing from that drawer. I dont know what company made the cupboard - so I dont know what type of runners to buy. I have attached pics of one of the drawers and also the inside of the cupboard where the drawers should go. Any suggestions as to how to get the drawers installed again would be greatly appreciated.
