crank pulley

I have a 1968 Dart, 1973 340, an aluminum water pump. The power steering pump and pulley is from a 71 Dart. It is a non AC car. The pulley I attached in the picture above is one that I thought I could use and is not from the 71 Dart. I can get that pulley but the car is buried in snow and I'd have to wait a while. If I can get one now it would be better for my build process. If not I'll have to wait.
