Congrats on the new purchase of the Elite Series Under-Bed Gooseneck Complete Hitch # RP30158-68 for your 2018 GMC Sierra 2500!

The adapter that you're looking for is the Reese # RP30156 which will give you the industry standard rail connection points that should work with your older 5th wheel hitch. Attached is a photo showing the tab locations so you can verify fitment.
