1963 Dart Wagon...broken auto tailshaft

The differences between '60-'64 and '65 transmissions are in the valve body only; no problem swapping tailshaft, tailhousing, or any other component throughout the '60-'65 year range. And a '60-'64 trans can be used with the '65 lever shifters (or a '65 trans be used with '60-'64 pushbutton shifter) by swapping either the complete valve body or just a couple of parts in it.
