That probably is how Dave checks the tires's air pressure! Right Dave?
Anyways, it appears in your latest photos that the center hump piece is separate from the two right and left liners is that correct?
Ban stick/tire beater .....It's a redneck one. Hickory with a lead core made and bought in Georgia when I was there last time.....haha
The piece on the drivers side has the hump piece connected to it and it just goes over the hump. Then the other side just fits in the footwell area. I should have pulled it out I guess and taken a pic. I just stuck the jeep in the garage. If you want, I will post a pic tomorrow?
