Dually to single wheel f350

Hi, am thinking about converting my 1989 f350 dually to single wheel drive. I dont tow heavy so dont really need dually. I know what to do in the front end but not in the back. I can get ahold of a single wheel axle from a 1989 f350. Before buying it, is it a bolt up? Will the other single axle bolt up right where the dually is?
Thanks
