'65 Barracuda drivetrain swap

Ok, my daily transportation is in need of some attention. The 318 is out of an early 80's Ramcharger with unknown miles and 904 is still the cable shifted original, odometer show 137K. The motor is burning and leaking a quart of oil every 300 miles and transmission is leaking at the front seal and slips going into 2nd when pressed hard. I have an opportunity to get the motor and trans out of an '86 5th Avenue with less than 90K that was wrecked in the rear quarter panel, costs more to repair than the car is worth.
I'm not worried about the motor swap, but what parts am I going to need to make the new trans work? Should I ditch the original console shifter and go with a Lokar set up, which looks pretty straight forward, or try to fabricate a bracket to use the original cables?
