Measure 60 inches from the top of the tub or 72 inches from the top of the shower pan and mark on the wall. Take another measurement from that high mark and move it in 3 inches and mark this as the installation point for the mounting bracket.

Remove the rotating connector from one end of the oval bar and cut the excess with a metal saw. Smooth rough edges with a flat file.
