Hy Suzy, thanks for reaching out!
The correct kit for your 2023 GMC Sierra 2500 is the Roadmaster Direct-Connect Base Plate Kit # RM86FR. The kit 31773 is for an older GM truck and I can't find the other part you're looking for so I don't know what that fits.
For a complete flat towing setup you will need a base plate kit, tow bar, safety cables, vehicle tow bar wiring, a supplemental braking system, and possibly a high-low adapter. If you do not have all of these components just let me know and I can make some additional recommendations for you.
