Power Brake Linkage

I could use some help. Does anyone know what these power brake linkages are for. I'm pretty sure E body but not 100% sure on the application or years.
The top one has CW stamped on it and the rod has a # 2N on it and has larger rod end
The bottom one has no letters stamped on it and the rod has a # 1N on it and has a smaller rod end
Thanks Bob

Believe 71 to 74 E and B. If bolt has attached extended sleeve it would be 70 E.

I agree with dragon. The one with the pin fits the 71 up booster with the smaller hole. The one on top could be a 70 with the bolt and spacer for the larger hole on the 70 booster. It uses a bolt with spacer and not the pin.

Thanks for the help. The push rods on both of them has the same size hole. They look different because the casting is bigger from one to the other.

He is not talking about push rod on the linkage, rather how the Booster rod attaches. In 71, they started using pins vice a bolt. The hole size in the 71 up booster rod was smaller and accepted a pin. The 70 and down had a sleeve in a larger hole and accepted bolt and nut. Your bottom pic has a pin in it, so 71 up

Thanks Dragon for clearing that up.
