There has been a loot of discussion on this at /g/E-Leadscrew
Depending on what parts of the original system that you have you can replace the arm that the change gears go on with a motor mound and a couple of toothed belts, some have mounted the motor on the tailstock end. I would recommend the belt because it prevents a bunch of potential problems and also gives you a misalignment coupler? and the reduction.
