Shift linkage for a 545 RFE in '70 Dart

Anyone have any suggestions for floor linkage for a 6.4/545RFE swap in a '70 Dart? Most of the sheet metal fab is done and it's time to think about shift linkage. Will factory linkage work and if so from what?
I've given some thought to paddle shifting the the car but I don't have any data on if it's good way to go, etc.
