As far as the body design, this is entirely up to you and your abilities to build it. The original concept of a flexi or leaning sidecar is fairly simple and with a bit of digging I am sure I can come up with some old pictures or diagrams showing how the leaning took place. Pretty simple, really.  The diagram I can provide immediately but the photos will take a bit of digging. Let me know.
