      the Detroit locker EAT187S160 is designed to fit Ford 9" aftermarket center sections with a 3.250" bore diemeter and custom aftermarket 35 spline axles only. your 1978 Mercury wagon will be a 28 spline unit and will use a EAT187SL-13A unit Unfortunetly there is no exact way to tell your axles spline count with out taking your axle apart. All passenger cars ar 28 spline unless they are some sort of factory high performance like a Cobra Jet engine etc.
