manual steering in a 68 charger just plain sucked, yes it turns when your moving but, being 51 and planning on keeping this car for a while, and a worn out shoulder, and not having a numbers matching RT car, why not? there is a pin that runs across the bottom of the shaft, that will need to be removed anyways, i believe I cut a little less than 2" off the end. Then when coupler was put on you need to drill two holes through the shaft to lock it in to the coupler. shaft is soft and drills easily. I believe the reason for cutting is to keep it in the range for the collapsable column which the steering column was engineered to do in case of a front end crash. good luck!
