Can the Mopar M20 hitch be modified to be compatible with sidewinder or revolution pin boxes?

The Mopar M20 hitch is the same as hitch as the Curt Q20 part # C16130 which features a spherical axial bearing to improve the pivoting of the hitch head. The 360-degree pivot is why its not compatible with a pivoting pin box such a sidewinder or revolution. It is not possible to lock out the head so there would be two pivot points in the towing setup which would not work.
If you have industry standard base rails in the truck, you can use the Curt E16 5th Wheel Trailer Hitch - Slide Bar Jaw - 16,000 lbs # C16115 along with the necessary Wedge # 30861.
