So I finally decided on a cb antenna mount for the LJ. The exogate tire carrier I have from Gr8tops was designed by Jeff Scherb, many people on here know him for the awesome stuff he creates for wranglers. Well a company is selling his JK heavy duty hinges and als selling a CB antenna mount that goes along with it. I emailed Jeff to see if it will work with my tailgate hinges and he said it would!!! This is great because I can't use the passenger side teraflex mount due to the hinge reinforcements and I don't want the use the driver side one because I plan on getting a gobi roof rack and will have the access ladder on the driver side. Jeff also came up with a rotopax/cb antenna mount that would work with my hinges but since I have a 315 as a spare it work fit unless I do flush mounted tail lights.

Here is what the rotopax mount looks like, wish I could have used this but I just don't have the room between my tire and tail light for it.

Update on this... I've recently done a prototype set of "wide swing" hinges for the TJ; they also work with the Exogate. The hinge pivot point is moved 3" outboard, so when the tailgate is opened there's 3 extra inches of space to hang things on the tailgate without hitting the tail light.
Here's a new prototype wide-swing hinge compared to a standard Exogate hinge that's been in service on my Jeep for almost 5 years:
These hinges can also be installed on a stock Jeep without an Exogate.
A Hi-Lift mount with CB antenna installed on the wide-swing hinges:
A 5-liter NATO can mounted to the wide-swing hinges:
In both cases the tailgate opens fully without the HiLift or the NATO can hitting the tail light.
The Rotopax carrier you posted a photo to would also fit with these hinges.
I'm also playing with the idea of a universal mounting grid that would work with these hinges (the NATO can holder in the photo above is mounted to the grid):
