short shifter for a justy

[Bgale04]

i came across these on cardomain, its a short shifter in a 2wd, but i know a guy who did a 2wd, to 4wd conversion on a justy, so im guessing he re- wired the 4wd button ontop of the shifter to somewhere on the dash, and i was wondering how you would do this, possibly cut it, then take a tap to thread it and drill the knob?? would this make it hard to go into gear, i guess not if this guy did it. any help would be great!
