I myself have never done it but I have seen a few in CJs so it can't be that big of a deal. If I was to do it I would get one and then pull my old one and lay them next to each other and modify it to bolt in.
Not sure any tilt column is a bolt in for a 70's vintage CJ. I had to build/modify the brackets to make a GM column fit in my 75. It took a little time, but it wasn't too big of deal.
