1965 Barracuda Auto to Manual? Advice/Thoughts?

65 Cudas are not in general high end cars, so originality is not a big concern. If it was a # matching 273 4 bbl car I would consider leaving it original. Me I love to bang the gears and I have changed over several over the decades. I am old and was raised up on, and learned to drive on a stick. Many younger people today have never drove anything but an auto.
