Expedition + Navigator / Aviator front clip?

Anyone have any experience with putting a Navigator front clip on a 97 style expedition. If you look at my profile closely you can see my bumper is crooked from barely rearending a lady who slammed her brakes for no reason. Anyways... anyone ever done this to a 97, and is it possible to put the new aviator front clips on an 97. Did you use a conversion kit like the caddy front clips for chevy's? I havent seen anything of the sort for navigators but then again i havent really looked hard.. so anyone with any experience on this?
