Barracuda Power steering pump pulleys

[CudaLou]

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

My two cents. What I think I have seen. Spoked pulley is usually from a Saginaw pump. Large solid was rather standard on most cars. Small solid was mysteriously on some cars. My original '68 cuda 383 has TRW pump with small solid. Not much help but others will chime in.
