You are looking at a remanufactured FM61 EM80MS Torque Converter pt#: F-58. Left over inventory from the attic of an old auto part store. Will fit all 1986-91 Ford AXOD automatic transmission models with Taurus and Sable with 3.0L engine. Stock stall speed. 11” diameter, 23 spline turbine, .825 pilot, 18 spline pump drive, no drive on hub with 1.655-1.658 bushing, 4 mounting studs, clutch type unit. I guarantee this to be a good converter.
