Saginaw power steering pump troubles on a bigblock

Im building a 440 dart, I first had a 68 TRW pump from my slant 6 but my pulley would not line up, found out rb pumps have a longer snout, I then purchased a new Saginaw pump and mount but I cant get the high pressure line to fit between the biscuit mount(r/b k frame) and I cant find a good older power steering pump. any thoughts ?
