Default Manual to Automatic

Hello Members,
Has anyone ever changed their SM420 Muncie to an automatic on a 250-I6 c.i.? I've been told going to something like a 700-R4 is overkill because it needs a special linkage that, if not installed correctly, can burn up the tranny in a matter of miles.
One recommendation, on 3:07 rear end gears is to go to a turbo 350 and do the applicable driveline adjustments, amongst other things.

Would putting a shifter on the hump be easier than getting a new steering column? Leg room is a must as it is already, the more room would be nice. Although I want to remove the stock steering wheel because of it's size - '64 GMC - and go to a smaller wheel and tilt option.
Any info or help would be greatly appreciated. Thanks!
