Going to do the swinging arm mod that i always said i wouldn't

Nice black RSVR swinging arm , so was wondering do i need a special tool to take off the locking nut and if so where can i get one from ........i'm sure i've seen it somewhere on here but can't find it ....
My only problem is it's starting to look to much like D-riders now .........not a bad thing for sure just as long as you never move to Cornwall !!!

deepest southwest falco flyer ..............
Black and Bronze , c'mon you know they're the fastest
