I did this about two weeks ago, and have been quite happy with it.
I was pretty much in the same position as you. I wanted to get farther extended, as well as bring my hands in and get more positions (I'd already chopped about an inch off each side of the flat-bar a while ago).
Sorry for no pictures, but here's how it went.
handlebars (how old is your 7.3? Mine is a 2008, and it fits a 25.4mm (1 inch, exactly) handlebar.) Picked up some bar tape as well.
The next part is the tricky part. My brake/shifters did not fit onto the bars, so I bought a long cylindrical file and filed down the inside of the connections until they fit. Slid them onto the bars, and wrapped the bars. The only issue is that you end up with a lot of extra cable housing, which I suppose could affect brake and shifting performance, but I haven't had much trouble with it. I will probably end up getting it cut down a bit, though.
I'm thinking that if I like this outfit, I may end up putting some bar-end shifters on.
