I just got our 79 CJ5 going again and decided I'd build a rack for it. This is my first thing to build using mig. I didn't take pics at every step but enough to see the progress. I welded 1/4" 2x2 under the bumper to act as receiver hitches. The platform is 1.5" 11 gauge, 1" 11 gauge on the top and 3"x1" 14 gauge for the top rail. I just have to get my swivels for the seats and come up with something for drink holders.
