Correct power steering cap for 70 Chevelle SS ???

[XXXGoldL34M20]

I usually don't get stumped on a question about 70 Chevelles but you guys always come through for me most of the time >>> What is the correct Power steering cap look like for a 1970 Chevelle SS. My car is a Manual steering car but I need to answer this question to share the proper info in my 70 Chevelle SS club as I have been getting a lot of requests for this question.
Is the one in the photo correct ? I am guessing the one I have in stock is for a 1969 unit with different Fonts than the 70 and 1969 has a vent hole and 70 does not? Are they all Metal or Plastic?

How about a bump for education.
