You will need.

Hard Drive
Gel pack/ protector / silicone case (what ever you want to call it)

Remove the two screws holding the handle on. That will allow you to remove the palm rest cover on this model allowing you easier access to guide the caddy cable and harddrive into this model.
Now install the cable onto the harddrive, then slide the protector sleeve on to the harddrive. It has large bumps on all 4 corners. You will need to trim the two ends down nearly flat on the end where the caddy goes for it to slide in correctly.
Pushing the caddy in you will have to stop some and shove the harddrive back into the sleeve some ever so often. The bumps on the end will help hold it into place, it is a very tight fit and won't just fall out.
Enjoy your CF-73!
