So you want to add a sidebar to the showthread page. You'd have to put all the stuff from showthread into a <div> that you want on one side and then add another <div> to the page for the sidebar and then set a width for both of the divs. Something *like* below (I'm never tried, so that's why I say like this):

<div class="right"> all the stuff for the sidebar</div>
<div class="left">all your thread stuff you want on the left</div>

Then for the css:

.right {float: right; width 24%;}
.left {float: left; width: 65%;}
