While I don't remember ever physically laying a FE windage tray on a Y, I don’t picture it even coming close to working. There is a FE windage tray in one of the storage buildings and if it’s easily accessible, I’ll lay it on a Y and see just how bad a fit it really is. On my end and for the Y engines needing a windage tray, I’ll use directional screen in the oil pan or incorporate the windage tray into the main support girdle.
