For what it's worth, in case anybody searches in the future, the profile between the 2004 Hidden-Hitch and the B&W were identical, slipped right into the square receiver, but the height of the shank was much taller on the B&W and the lock shaft holes were a few inches off. Close, but no cigar.
I ended up buying a Reese Goose Box replacement pin box, was on sale yesterday...
IIRC the Companion has a square receiver while other goosenecks tend to have a round receiver. The Companion has a square shank that goes into the square receiver which gets latched in by the handle in the wheel-well of the truck.
I havenโt seen a shank for Hide-a-goose that would work with the Companion.
Now, the Andersen Ultimate Fifth Wheel hitch would work great with your current hitch and use the ball that Your hitch uses.
Thanks!
