sanderson DD9's with power steering?

Here's a picture of the DD9's on a 66 Barracuda from a car show up in northern CA. I'm about to buy a set myself for a 65 Valiant. I contacted Sanderson a while back and the guy mentioned that the original DD9's will fit an early A-body with P/S and an automatic. From what I understand they are supposed to fit pretty easy......
