Thanks Robert and Jim. I am now clear that I can use the 235 flywheel,clutch, starter with my 216 bell housing. Since I am already with a 12 volt system in the 51, I just thought it better to use the later 12 volt starter not to mention all the new looking clutch material in the 235 bell housing. I will know more when fI get thhe 235 bell and flywheel off tomorrow. I just couldn't figure why most were using the old six volt starter unless it was they hadn't already converted to 12 volt. The old 6 volt starter I have been using was still working well with 12 volts when I pulled the 216 engine yesterday. The guts of the 216 bell housing look a mess compared to the shinny 235 which I bought as having 3,000 miles on rebuild.

Thanks, I know know enought to keep from getting into real serious trouble as I proceed. If it was one of my old t models, I would know a lot more about the situation.
Bob
