You see the cross member/brace running on your floor? Its that bump about 8-12" behind the shifter. If you feel around on your carpet you might be able to feel the holes in that brace for the console front bracket. I have vinyl flooring but was able to feel the holes and confirm it with a small ice pick. If so thats where you want the two holes for your front bracket to mount. It looks like you have the console very close to being in the right spot. They don't leave a lot of room for tall cups with out the shifter getting in the way. I have the dual cup insert in my FX4 shorty console and with 32 oz drinks I have to use the second cup holder thats farther away from the shifter. If I have smaller drink I can fit it in there and clear the shifter.
I'd be interested to know if manual trans trucks had shorty console option and what insert they used.
Well I did some research and its the same console I have.
It looks like the FX4 shifter gives more clearance for the drinks.
