A thrust reverser of a nacelle is orientated at least in-part about a fan case of a turbofan engine. The thrust reverser includes an outer fixed structure assembly and a radial spacer. The outer fixed structure assembly circumferentially extends about a centerline and is spaced, at least in part, radially outward from the fan case. The radial spacer is engaged to the outer fixed structure assembly and is in sliding contact with the fan case.
