While I've really been happy with this build, the box is just too small and I just don't have enough room to ever clean up the back. My best DB drag style number to date was 153.1 but I'm pretty confident I'm not going far beyond that. I'm never driving with passengers these days so the rear seats are getting traded off for some proper box space and hopefully some decent SPL gains.
I had somewhat planned for this eventuality and the old box came out in perhaps an hour and a half with a sawzall. For the record, I taped trash bags to the sides and spray foamed into them to fill the sides without being a sticky mess. Going forward, this will be very permanent.
Sadly losing the back seat doesn't let me really get more height. A few inches, but not worth the hassle of building all the angles. I decided to put batteries up there though for a few reasons. One being to keep the back cleaner and possibly be able to open the back wall to use it for cargo space in a pinch, and another to distribute the weight a little better since I do some rather heavy towing about once a month.
I want a solid seal to the sides but the way this Jeep is laid out my seat back wants to be well past the B pillar so building solid to that is dead. This is not so much for strength, but just for a mounting point and to seal off the front. Cosmetic panels will be built later for front and back but this is going to be what really seals the pressure up front. Using just scraps laying around mostly to build out the sides to where the walls will begin. The angles of this are really all over the place so it was quite the jigsaw puzzle.
