I have 1995 4WD 2500 truck with 8,800 GVW. My son had an accident with it. Took a hit on the RF wheel which pushed the axle back,bent control arms and snapped the pitman arm off of the steering box. Do not see any frame damage. Insurance company totalled it, but I kept it with the idea of using it as a parts truck. However, I have decided to resurrect it. Since, I have to replace the steering box, I am thinking of upgrading the steering box. Will a 3rd or 4th Gen box bolt up?
