Nix, sounds like the same CB I have, the 29 Nightwatch.
A good place to put it is below the glovebox on 2nd gen 4Runner type interiors, and also that is where I have it now on the FJ.
It does not interfere with the passengers legs at all.
91 4Runner
And in the FJ same spot
The mic now resides on the left side so the cord does not hang out like in the picture.
