1965 Barracuda Auto to Manual? Advice/Thoughts?

Hello everyone. I have been reading a lot of the forums on this topic and just wanted to get some additional input from anyone willing to help out. I recently picked up 2 1965 Barracudas. One is a floor shifted auto and the parts car was manual trans car. I believe the previous owner was going to make the auto car into a manual, using the parts from the other one. I am torn on if I should or even want to follow that same route. I believe I have most of the parts from the parts car to do the conversion, but wanted to see if anyone cared to chime in if it is worth while doing if I am just looking for a driver car. Or am I better off just selling the parts car and sticking with the auto?

Thanks in advance.
