Rear dresser bars w/Beetle Bags?

Has anyone found a source for a rear dresser bar that will fit the bike with the Corbin Beetle Bags? My dealer showed me the Beetles installed on another Rocket (I don't get my bags/bike for another week) and it's clear that the Triumph bars won't work; he didn't have any suggestions other than having something custom fabricated.
Thanks

I have another query on beetle bags. I did e-mail corbin, but no response from them. I take delivery of a R3 Classic this week (with rear dresser bars - $h1t!). I have not yet ordered beetle bags, as I have access issues into my yard. Does anyone know the width of the rear end with beetles fitted? I'll take answers in inches, metres or carrots-per-cubic-fortnight, but I do need to know before I spend about £700 on bags that then won't fit into my yard without major surgery to a 7' high wall.

Thanks in advance to anybody who can help me on this one.

They are 36.5" across at the widest point.
