Adding a side border to the primary sidebar widget

I used this code to add a nice rule separating my primary sidebar from the main section of my home page:

}

.sidebar-primary {
border-left-width: 2px;
border-left-style: solid;
border-left-color: #c0c0c0;
padding-left: 14px;
}

The problem is I would like the rule to show up on the right side of the sidebar on my inside pages. Any ideas for how I can make that happen?

Here is the where the rule (border) shows up correctly on the Home Page:

And here is where it is on the wrong side of the sidebar on an inside page:

So my challenge is to have the rule on the left side of the sidebar on the Home Page but the right side of the sidebar on the inside pages (where the sidebar is on the left side of the page). Any suggestions?
