Trans swap info

Hi everyone
have a question i have a 1962 falcon with a 170 6 cyl and a 2speed trans want to change it to a three speed automatic does anyone know what will bolt up to the block any help will be appreciated

 

They had a "green dot" three speed auto in 65 falcons. That would bolt up but may have to do something with the crossmember mounting. Also, the detent in the column would need some work to make you be able to select all 3 forward gears. TFFN.NET is a great resource for info on this swap.
