I have a 95 wrangler with what I think is a Rugged Ridge oversized, A frame spare tire carrier that is missing the 2inch square, vertical post. I've made a replacement with some square tubing I had. My question is how tall is that vertical post supposed to be? I have plenty of length on the one I made so I just need to cut it down to the proper size. Any members have on they can measure? Thanks in advance, Robert.
