My vote is for a 261! Be patient when looking for one. They come up from time to time. A full pressure 235 would be my second choice, and are easier to come by. No sense going back with a 216 in my humble opinion. Others will chime in with more details regarding what to look for but most of your bolt on components will transfer over from your 216 to a 235 or a 261. Time for new clutch when your there, lol!
