Rod End Spacer

[xs420240sx]

I'm trying to design a rod end spacer, I successfully designed the basic shape of it, but now I need to further refine it a bit. Can someone point me in the right direction as to how I can remove part of the side so that it matches the black spacer?

Even better is to use the Revolve feature.
