In case it helps someone else, I've just successfully fitted some 60cm IKEA Utrusta wire basket drawers (IKEA article #002.046.72 ) in an old discontinued IKEA Faktum kitchen cabinet that's been customised in the past for use as part of a fitted bedroom. I found that using the shims (the plastic packing intended to be sandwiched between the cabinet side and the metal runner) included with the Utrustra drawer runners made it too tight for the drawers to be inserted so left them out. I assume the internal width dimension of the Faktum cabinet is 1 - 2 mm smaller than the current IKEA Metod cabinets. Photos attached...
