So is there a way to redrill the flanges to make the CV work on the rear? As far as running dual cases there is really no reason for me to do it because this is a mud / trails truck from Minnesota, so I really do not need the extra gearing. Also keep in mind that I am going to keep the lift pretty minimal (under 3") on this, so that should help some with this. I have also thought about pushing the front spring mounts an inch forward or so because it would help me with a few other problems at the same time, so that further halps the driveline situation. So...square shaft up front built out of the stock front and rear built using a front CV with a redrilled flange then?
