Ok, get a set of those Shimano cable stops that the guys linked to. Take the little piece off the other side, you won't want it on there when you have the Shimano cable-stop dealiebobs. The little piece is part of your shift lever, not part of the frame.
Your local bike shop probably has a set of the Shimano cable stops lying around that they could sell you, if you want to get along with your project right away.
