1997 Ford 350 Custom

I currently own a 1997 Ford 350 7.3L Diesel, Crew Cab Long Bed. After considerable time spent saving and earning to buy the truck now I'm working on customizing it. However, in my pursuit for better interior comfort I'd like to completely replace the front seats (40/20/40) with something similar. I'm going to have it reupholstered, however i also desire to install power seats, currently the only power to the front seats is for a broken lumbar support.

Any suggestions? Does the current power provide enough to power modern fully options electric seats? Any particular set of seats that would fit best without having to buy something brand new via online?
