well i just did the 01-03 f4i tail swap. Everything turned out perfect except a few small things... the wires for the computer and fuses are longer for the 05 model (i think) once i swap it to the 03 tail, according to manual the computer sits on top of the battery tray, but my wire is too long for that -_-.... what did you guys do ? where did you put it? my wiring is a mess in there right now ><
