Information please

Hi everybody . I decided to treat myself to Honda colour matched top case , so contacted my dealer here in Essex UK . I was told that the box was readily available but the fixing plate was discontinued and none available . This is strange because I doubt they will sell any more boxes without the fixing plates .
Does anybody know where I could get one or do the boxes connect to any other brand of plate ?
Safe riding to you all.    Alan K

Chances are the box fits many hondas, the plate will be sw specific.
Try ebay... or just go givi, kappa, etc
