You can go to the above link and order an adapter. The *57 swingarms are predrilled and tapped for an adapter that saw the light of day but the Hammerhead works.

Also you can make your own.  A few here have done both.

this is a Hammerhead for my Oz, the 857 Hammerhead is similar in design but a little different because the dropout is shaped different, for one thing. you are looking for something like this one, i think ???

i used to have a detail explanation of how to build one on my old site but when i changed servers - it disappeared.

somebody here said they saved it, might be somewhere on the old site somewhere

not that difficult to make tho' -
