Barracuda Power steering pump pulleys

I have 2 barracudas and have spent a lot of time finding all the parts to make them power steering cars.
Car #1 is a 68 Barracuda 340, I'm using a TRW and have all the parts, but do not know what the correct pulley is on the pump?
Car #2 is a 69 Barracuda 383 I'm using a federal and have the same problem, I don't know what the pulley should be.
I have seen 3 different types of pulleys on these pumps and there's probably more. The 3 I have seen are: a small solid, large solid and a 3 spoke that's pretty large. Can anyone shed some light on what is correct for these 2 cars? Pics would be great. Thanks, Lou
