I understand now.I think my 09 EG Classic has mounting tabs on both bag supports.But I just checked a set of 09-up SG bag supports I have,and sure enough,no tab on the right side.Sorry I can't help ya.

 

too expensive for just a dummy antenna. Having dealership put n new 2013 Hogwired Sixpack so ill just have em put BOOM hidden antenna also.

 

I just bought the tour pak quick detach kit for my '09 FLHTCU (PN 70032-09), which comes with the AM/FM antennae relocation kit, but not the CB mount. The AMFM does not just clamp on, but mounts to a tab/plate on the saddle bag frame. The CB antenna kit (PN 76410-09) is a clamp on that would not match the left side exactly. Finally discovered that the harness kit PN 53246-09A had the exact mirror image mount for the right side.
Both those kits have parts you don't want/need. The parts for the mounts only are these:
Left side (AMFM) - PN 76557-09
Right side (CB) - PN 76504-09
For each one you need two torx screws, #10-24, PN 2441
These part numbers and more, for lock washers, antenna adapter, antenna cables are on the back page of the .pdf instructions for the QD kit and harness kit, PNs above.
But if the SG does not have the tab with screw holes (per dansflhti), you're SOL, and will have to use the clamp on. But maybe this info will help another Glider...

 

I just confirmed that the EG Classic bag supports have the tab for mounting an antenna on both sides.
