I used the stock sway bar but I took it to the press & bent the ends inward 1" per side.. All I did was set the bar in the press with the 90 degree bend that forms the arm centered across the bed of the press, I used a piece of 3/8 flat bar as a press adapter to fit into the "V" formed by the bar & applied force... The bar bends easily & all I did was measure between the arms till each one came in about 1"...
