We do have adapters to allow the Roadmaster Base Plates, # 172-5, to work with Blue Ox tow bars. If you have an Aventa, Aventa II, Kar Bar, Aladdin, Alexxa, or Acclaim RV-mounted tow bar, or an A-frame Blue Ox tow bar with 1 or 3 pronged attachments, you can use RoadMaster Base Plate to Blue Ox and Demco Tow Bars Adapter, # RM-033 or # RM-032. Base plate installation can be moderately difficult, but if you have experience with automotive projects you will be able to perform the installation... view full answer...
The recommended ball mount to use on a 1997 Chevrolet Lumina with the Draw-Tite Trailer Hitch 24628 (DISCONGTINUED) is the Draw-Tite Ball Mount, part # 3592.
The ball mount that you referenced, part # 3594 has too much of a rise and is not recommended by Draw-Tite to be used on the Chevrolet Lumina. With Class I and II hitches, the ball mount recommended by the hitch manufacturer must be used, not doing so will void the hitch warranty.
I have linked an FAQ on hitch ball mounts. view full answer...
The Draw Tite hitch part # 24628 that you referenced does not come with a ball mount. That would have needed to have been ordered separately.
The recommended ball mount is the Sportframe Ball Mount part # 3592, for a 2 inch ball part # 19258, for a 1-7/8 inch ball part # 19256.
For trailer wiring you would want the Draw Tite Wiring kit part # 18252. See install video. view full answer...
