I have been thinking where I can put my two recovery bags when the seats are folded down and I am filled with camping gear. I thought it would be a perfect fit for them behind the driver and passenger seats, however, in the WJ the lower section of seat folds forward and occupies that space. After a little JF browsing I found a couple threads for the WJ rear seat mod. Check it out -
I started by unbolting the brackets from the floor and then removed the brackets from the seat bottoms. In a vice, I carefully drilled out the mushroom side of the rivet pin with a 21/64" bit.
I tapped out the rivet pin and bored all 8 holes to 21/64":
I used 5/16"x2.75" wire lock pins for a means of quick disconnect when I want to utilize all the cargo room. Perfect spot for my recovery bags, and leaves the entire back of the Jeep open for gear!
