Tim, George,et al. The 216 is long gone replaced by a 283. Also the burb is in storage, cold storage I might add. Not going out @14 below zero for S/N.Although my 49 has barn doors during rebuild I did notice that the cables and hardware for clamshells were in the walls @ the rear of the truck. Maybe common practice @ the factory so either option could be used?
I can always further my education on stovebolt.
