03 Magnum 2×4 rear end parts needed

My son and I have gotten in to riding again and my daughter has showed an interest in getting in to it with us. I have a bike for her, a 03 330 2×4, but the only issue it has is the driveshaft is stripped at the rearend. It has appeared to have damaged both the rearend side splines as well as the driveshaft splines. Does any one out there have any parts?
