Has anyone moved a side case rack from a 2013 or 2014 to a 2015 or 2016 DS? They have different part numbers but I don't know how different they are. My 2013 is not back from the factory yet with a new battery so I can't try it on my DSR. If it won't work without a lot of modifications I'd like to order a new rack and not keep waiting. I had to do some modifications to my 2013 rack because of the tail-delete (build a custom brace) so I'm willing to do some (not a lot) of fabrication.
I only had to enlarge the seat bolt holes to move the top case rack to my DSR. I had already changed the base plate so I could use my GIVI V46 with LED running, brake and turn signals. I moved the smaller GIVI and base plate that came with the 2013 DS to my 2012 S.
I put my smaller slipstreamer windshield on the DSR because the fork clamps for my large slipstreamer are still on the bike at the factory. It looks like the small windshield added about 5% to my range based on my 29 mile commute for 5 days with and without.
