There's a trick to getting those P/S pumps tight again, but I don't remember it. Back when my '66 New Yorker was a daily driver I jammed a chunk of wood down in the bracket to keep it tight. It had been fine until I loosened it for some repair I was doing, then was never able to get it tight again. I may have just not had the right tools back then to crank down hard enough on the bolts. There's also a rubber bumper on the bracket that wears out/falls out.
