I can't remember how many bolts but I do remember that it was a lot easier after I dropped the column from the dash. The box on top of the column close to the floor houses the ignition switch. I have replaced both the one on my XJ and the one on my MJ. XJ was a struggle because I was just learning about them many years ago. The MJ was a breeze with a little experience under my belt. It is a daunting job until you have done a couple then it only takes about 10 minutes from start to button up.
Hope this was at least a little helpful.
