you need the pulley as you've mentioned and the entire bracket assembly for non ac. I did this and it worked. I still needed to add a washer behind the pulley as well as machine a little off the inside of the pulley so the nut could bite on the short threaded shaft off the alternator. It worked perfectly by I took some time to get it dialed. I used a lathe to remove some of the material from the pulley.
