I adapted a Honda Shadow VT750 Aero VT750
Cost now $ 59.46 US on E Bay from Atlanta Item 130589482562
Slightly different shape
Only minor modification at the front is required to fit the existing screw holes in the fender.
The rack mounting plate is shortened & two 1/2 holes drilled to suite the spacing of the ones in the fender.
I have a fender mounted backrest and the bracket covers it all up & holds it on.
If you dont have a backrest then a plate could be made to hold it in place..
The modification is all hidden under the lambswool seat cover I have on the solo seat.
I dont know how to post photos but if you contact me at :-
littleford@hotkey.net.au I will send them.
The photos also show how I relocated the aerial.
