NEW YORK — Dickstein & Co. LP said it has retained Rothchild Inc. as financial adviser in its bid to replace four directors on the board of Hills Stores Inc.

Dickstein said it selected Rothchild because Rothchild’s Wilbur L. Ross Jr. had advised the unsecured creditors’ committee in Hills’ Chapter 11 reorganization. Hills emerged from bankruptcy in October 1993.

Dickstein, which holds a 12.6 percent stake in Hills, is seeking four seats on Hills’ eight-member board.

Hills stock closed Thursday at 22 5/8, up 1/8 on the New York Stock Exchange.
