1969 GTX p/s question

I have a 69 440 GTX that has a federal p/s pump on it. The car was built on 3/69. I believe it should have a Saginaw pump with cooler (4:10 DANA). There are two sagenaw pumps. One has a nut to retain the pulley & the other does not. I also believe it is a 3 spoke pulley. Can anyone confirm what I need?

my 69 gtx supper track pack 440 engine has saginaw pump spoke pulley with a nut. I don't know if it wea on the new but was on it when I got the car

These things do get swapped through the years. I did not know what I had was wrong until I started looking into it. According to my factory parts book it is a saginaw with a cooler but wasn't sure of the correct style. The only way to know for sure is a picture from the day or if anyone had a true survivor. Thanks for the reply.

Are the last digits of the power steering pump part number listed on the build sheet?
