Is this what you're looking to do? This is a 2006 trek FX 7.3 that I rehabed, including the drop bar. Changes for just the dop bar was the handlebar itself, brake levers, bar-end shifters, cabling for brakes & shifters, and bartape. I did t myself on teh cheap; already had the bars and non-aero brake levers, bought the bar-end shifters on line for cheap (came with cabling), and bartape at my LBS. Not the lightest or fastest bike, but its a great comfy workout bike. And the drop bars are a lot more comfy that flat bars.
