I don't have the Menace apes, but I do have 16" Carlini Gangsters on my '15 RGS.
All of my extensions came from Drag Specialties.
Hydraulic Clutch Line +10
Part number for the clutch line is 0661-0008.
Break Line Kit +10
Part number for the break line kit is 1741-3999.
Wire Extension Kit +12
Part number for the wire extension kit is 2120-0369.
I haven't experienced any problems with any of their products and I also ran them for the 16" apes I had on my Road King before this bike. Hope this helps.
