Roadmaster Sterling to Blue Ox Faceplate

I had the same situation. I have a Sterling All-Terrain towbar that I used with crossbar on my old Chevy Tracker with Roadmaster baseplate. Then I bought a slightly used new to me tow car that already had a Blue Ox baseplate installed.

Yes, I ditched the crossbar and just swapped out the ends of the Sterling towbar with adapter ends that would match the Blue Ox connections on the car.
