I have a 2016 X6 and need to change DL to 29.5 which manual shows to be T2-B2. Will all the 2014-2015-2016 mods work or did Xpedition change the mods in the 2016 model? I have checked for part numbers online and have not found anything to check to see if part numbers are the same on different year models. Will all X6 mods work on all X6 models?
