I have run around a bit with the center console now and the way I have the CB, the shifter Barely touches the edge of the CB in 2nd. doesn't hit in 4th or 6th...
The height of the armrest seems to be about the same as before. one note though. you lose the use of the rear cupholders that pull out if you have it. the drop box for the cooler goes almost all the way to the floor. you can run wires under it and so forth... .
I added some foam to the inside where there is some spray in foam for the cooler. I will try it out sometime and see how well it insulates.
