I am looking for a specific basin strainer for one of two sinks in a vanity unit. Cannot find anywhere. Not standard. Will have to change whole waste system both sides if I can't find one. Waste system is designed for the unit so it leaves room for drawers. Depth of strainer about 15mm. D = 64mm. Middle screw hole 14mm for hollow screw. Screw is 16mm top, 38mm length, hole diameter approx 6-7mm. Please see pictures in attachment. Would be so grateful for any advice. Thanks
