Without knowing the exact nature of your existing trailer and how the coupler attaches to the trailer, I can't prove a specific adapter, but I can show you what we offer.

We offer many different adapters that would replace the coupler on your Gooseneck trailer if it has a square or round tube coupler. I've linked you to the adapters we offer. To choose the correct one, you'll need to know the inner diameter of the outer tube that the existing coupler slips into. Also, you'll need to know if your existing coupler uses a series of holes for height adjustment or set screws. Some like the Bulldog # BD0289580300 would require that the existing tube be cut off and the included outer tube be welded in place.

The # AM3100 is designed to tow a fifth wheel trailer using a gooseneck ball, which is the opposite of what you're trying to do.
If you'd reply with a photo of your existing coupler and a measurement of the inside diameter of the tube that the coupler slides into, I'd be happy to provide some specifics.
