The Police Diplomat/Gran Fury had a larger front sway bar if you can find one in yard. Also grab the rear lower spring plate with the bracket for the rear anti sway bar that came on the AHB and the bar and frame bracket too if you can. I know this pic isn't all that helpful, but here's what the bar looks like. I was holding it after removing one I already sold but you can see shape and frame bracket
