My tailgate is actually in pretty good shape with no rust at the bottom like most that guys are having to repair.
I want a flat tailgate because the tire carrier that I'm going to build will have the same lines as the traditional slanted tailgate that the Jeepster is known for. I was going to look for a flat tailgate but I really like the large "JEEP" that is stamped in the right side of the humped tailgates.
