I have a 1969 GT500 A/C car that needs a power steering pump. I have two pumps, both without tags. On one, the nipple goes up and the other it goes straight out. I do have the correct pulley but with all the surface aging, I am not sure of what finish to take it back to. Two questions, if I may. Does the return nipple go straight out? And second, what finish/color (and shade/degree if black) is the pump pulley.
