I'm sure someone in your neck of the woods with a set of happy trails racks wouldn't mind coming down.
Fitment should be easy, depending of course what cases someone is using their happy trails racks for. I for instance have a set of GIVI cases which use two mushroom shaped thingies and a pyramid clamp so the case stays on the outside of the rack.
If someone is using the pucks mounting system then they would need room on the inside of the racks to accommodate the mounting system.
