I would definitely follow Pete's advice being that he's built a couple. I'm a fabricator that's built everything you can think of, but I've never tackled a sidecar so I'm sure for me there would be some trial and error and cussing involved lol.

But to answer your question yes, welding a pipe with gussets to both frame rails side to side under the engine cradle. And attaching the rear to the right side of the swingarm with a long slotted gusset. But I wasn't factoring in what Pete said about turning, so maybe my idea wouldn't give you enough lateral stability with the wheel mounted further back. I'm sure you can find some diagrams of different mounting methods online.
