I can't really help you but I suggest that you make your own.
I jsut picked up a 05 DJ3 and mad emy own bracket to mount a std steerer tub mounted fenter. It replaced the stock unit and fit the curve of the Marz funky crown and cleared the arch. All it takes is a strap of metal appropriate for the bracket, a vise (to use in bending) a hammer or cressant wrench to bend with and a drill. Some time and tweeking you can make it fit.
I ended up using a wedge (not a star nut) in the steerer tube, because the DJ3 steerer tube is so thick my star nuts wouldn't fit.
With some time and patience you can make it work......unless I am missing something. It can't be that hard.....but maybe a stock fender will not fit. That is where you come in.....modify it.
Marz makes an '06 flat crown that fits a fender now... I wish I would have known this last spring when I bought my flat crown... they also make a supper drop upper like for a durado... I've seen the flat crown 888 w/a The up at whistler afew times...
