Most people go the other way and remove their auto 44-44 to install the 'real' 44-45 4wd xfer case.
I would have given you everything you needed for free - I threw it all away about two years ago when I swapped in the 44-45 case.

MY 19 has the new BW 48-11 case and stuff. They changed the shift points (has 40 different points) and the engagements for the 4 X 4, a lot smoother. But, of course, U still are running a case with clutches.
Auburn Hills, Michigan, March 27, 2018 – BorgWarner debuts its Electro-Mechanical On-Demand (EMOD) transfer case on the 2019 Ram 1500 4x4 pickup truck. Building on BorgWarner’s proven Torque-On-Demand® clutching system, the new EMOD technology delivers faster response and higher torque output for better on- and off-road performance. For automakers, the scalable system offers easy traction calibration and integration for a variety of vehicles, from small SUVs to heavy-duty pickup trucks.
“BorgWarner’s new EMOD transfer case features unmatched clutch control and actuation capabilities,” said Dr. Stefan Demmerle, President and General Manager, BorgWarner PowerDrive Systems. “BorgWarner has supplied on-demand transfer cases to Ram since 2010. We are proud to introduce our latest advancements in the next-generation Ram 1500.”
The heart of BorgWarner’s new EMOD transfer case is a motor-driven rotational cam mechanism which provides both robust clutch control and range shift function. The active clutch actuation technology delivers higher torque output, linear clutch response and pre-emptive clutch locking torque with zero rear wheel spin. For hill parking, the system offers the capability to hold front/rear locking torque when the ignition is off. In addition, the EMOD transfer case is equipped with BorgWarner’s HY-VO® driveline chain, optimized for high efficiency and durable performance.
